Corvette BibleCommon Problems Common Problems Leaking Battery Many C5's came with AC Delco Freedom batteries that tend to have the case crack near the battery posts. The leaking battery acid would drip down the side of the battery, down the funnel-like battery support, straight down onto the PCM and the wiring loom. It can also get onto the A/C lines. I believe they are the vacuum lines that control the movement of the interior vents, and usually the system will default to blowing out the defroster vent. Sometimes car crippling damage would occur, sometimes not. It worst it would mean replacing the battery, the PCM, the wiring harness, grinding the rust off the frame to repaint it, changing the A/C lines and possibly swapping out another computer as well. This mostly happened on early C5’s because later C5’s used a gel-type battery that cannot leak, but I believe the problem resurfaced on ’04 or ’05 models again. Check this out before buying a C5. Use a 8 mm monkey wrench, preferably a ratcheting closed-end version, to removed the battery cables. You also remove a holding block on the front side of the battery. You will need a long extension to reach it. The battery lifts out, then remove the black plastic battery tray. Look under the tray for rust or white powder--signs of evidence of battery acid damage. It would probably be best to move to the next Vette unless you don't mind possibly tackling this repair in the future. It's possible that the car will throw codes for no apparent reason. No matter what Vette you buy, replace the battery with a gel-type battery, like the Optima Redtop, sold at CostCo for $100. Grounding Problems aka CRAZY electrical gremlins! Bill Curlee has a great thread on the problems that corroded ground connections can create, and how to clean out the grounds. The most problematic ground connections are behind the headlights on both sides. Check out Bill’s thread for detailed info: Go! Here’s where all the grounds are: Go! Water Intrusion Water leaks have several ways of getting in the car, and none of them AFAIK are very difficult to fix. Proper adjustments and maintenance will prevent most leaks. Bill Curlee’s thread abouting locating & cleaning the udders, and sealing the door hinges. Here’s a few TSB’s from the CorvetteActionCenter.com: 1997-1998: Service Bulletin: Waterleak Above Door Glass (Reseal Blowout Clip) 1997-2002: Service Bulletin: General Waterleak Guide 1997: Service Bulletin: Water Drips into Rear Compartment After Hatch/Glass Has Been Opened Seats Corvette seats are delicate. Sliding hard across the bolster can break it, causing it to flap side-to-side. The leather is cheap, and there's little protection for it. It will wear out and form cracks, which is normal…for cheap leather. The wire springs in the seat bottom, and the bars in the bolsters can also wear thru the foam and leather, but that can be fixed by placing layer of burlap between the springs and the foam. Check the black plastic surround on the bottom of the seat to make sure it fits snugly against the leather, and isn't cracked. Older style plastic surrounds had a tendency to separate from the seat, but could be pushed back in. The newer style plastic surrounds can be used as a direct replacement, but one of the plastic studs may need to be ground off, or a hole will need to get punched into the leather. The seats tend to rock back and forth by about a 1/4" during acceleration and braking. It can be fixed, but GM will not fix it. Some lucky owners can get the dealer to replace the frame under warranty. The seat backs swinging forward under braking is normal, and not considered a problem. Here are a couple fixes: Corvettemechanic.com --- must be a member Rocking Seat Fix Seat choice Get the sport seats. The sport seats have a hole under the headrest. Some people put racing harness belts thru those loops. The seat frames and foam in both seats are interchangeable. Harness belt holes can be installed using Ford harness cutouts. Ask the dealership for them, they should know what it is without a part #. The foam in a standard seat will need to be cut, and sewing will have to be done, but it’s an easy job. Headlight bezel plugs There are 1-1/2" plugs that are located on the headlight bezels that would fall off on the older Vette's. The new style plugs, have a twist-lock to prevent them from falling out, but also requires new bezels. Only the new bezels & plugs are available now, and they are compatible with older C5’s. Headlight gears The gears in the headlight motor are plastic, and wear out over time. Ice, heavy Euro or projector headlights and twilight sentinal will cause the gears to wear out quickly. Fortunately a few years ago, Rodney started selling replacement brass gears, check out his website. Corvette America and probably a few other vendors now sell their own copy of his brass gears. Here’s a thread that shows how to replace the gears. Replacement nylon gears are also available from Motormite Help!, part #42400 for $10-13. Src To replace:

The wind noise will never totally go away, but if there's creaking, you can eliminate that by thinly applying dielectric silicone grease to the weather-stripping. It also prevents cracking, so do this to all weather-stripping, on any car. Also, the plastic beneath the roll-hoop may hang low and rattle against the attachment points of the roof. A dremel with the drum sander attachment quickly provides the clearance to eliminate the rattle. Hood rattles During cold weather the rubber hood stops can also rub and rattle against the hood. Adjust and lubricate the rubber stops so when you pull the corner of the hood up, it doesn’t pull up, but the hood still closes. Drivetrain rattling The valvetrain makes a significant amount of noise at idle. It may sound like sewing machine. Converting the valve rockers to true shaft-mounted adjustable roller rockers with may help eliminate the valvetrain noise if adjusted properly. Installing a big cam and stiffer valve springs will make the noise louder. On manual transmission cars (M6 or M12), the transmission sounds like it is rattling when leaving the line. It is normal. It is the clutch throwout bearing rattling around. Sometimes you'll hear a horrible rattle if you shut off the engine. If you press the clutch pedal in while shutting off the car, you won't hear it. Shaky braking The front brake rotors warp easily under heavy braking…or at least that’s what uneducated drivers think. I tend to believe StopTech: http://www.stoptech.com/whitepapers/...otors_myth.htm I verified this by lightly grinding my rotors with steel wool. Garnet paper is recommended, but I haven’t tried it. If you insist the problem is warping, don’t turn the rotors since thinner rotors warp more easily. Resurfacing the rotors is only a temporary fix, one that is less effective each time your resurface the rotors due to the reduced thermal capacity of the rotors. Rotors are available for $25 at Napa and RockAuto.
This parking brake can present when the rear rotor is taken apart. I
have an ongoing problem with my right parking brake. After leaving the
parking brake on for a prolonged period, or during very cold weather, the
parking brake tends to drag and cause a squeek once per revolution of the
wheel. After driving for a few hundred feet, the sound usually goes
away. Sometimes backing up and pulling the e-brake can make it go away
immediately. That procedure is supposed reset the e-brake, but I don't
know why it occasionally and temporarily fixes the problem. Here's a
diagram:
 Scraped front ends and rocker panels Checking for scrapes is an easy way to tell if the car was treated well. It's almost impossible not to scrape the front end, but there are two metal crash bar loops that should prevent the bumper from scraping. The bumper itself should not have scrape marks on it. Check the underside of the tip of the bumper, and the bottom corners of the bumper. If the crash bar gets scraped enough, eventually it will wear down to the point where it needs to get replaced. It costs about $220 for the crash bar, nut-serts, bolts and insulators, and can be replaced in a couple of hours, just be sure to hook the hoses and electric connector back to the A.I.R. pump. Here’s a list of ALL the parts you’ll need to replace the impact bar and the side air deflectors: Part #------Qty---Description 10188023---001---Insulator (goes to bottom of radiator) 10278679---001---Insulator (goes to bottom of radiator) 10278679---005---Nut 10400765---001---Plate (the actual impact bar, unpainted) 10419312---001---Panel (air deflector) 10419313---001---Panel (air deflector) 11515638---010---Nut-speci 11515757---010---Bolt-Metr 10281487---010---Nut Not all of these parts need to get replaced, and there will be a few leftovers, but it will get the job done. The rocker panels tend to get scraped on lifts and big speed bumps. A & A Corvettes invented two products to prevent damage from both kinds of scraping. They have wheels that attach to the crash bar, allowing the car to roll on driveways instead of wearing down the crash bar. It will still scrape the spoiler, but the spoiler is a cheap wear item that takes only 2 minutes to replace without a lift or jack. They also make two aluminum strips that attached the frame next to the rocker panels, and they take the scrapes themselves instead of the rockers panels. Neither of the devices are visible unless looking under the car, and they are discreet enough to possibly be missed anyway. If you see these devices installed, you can be pretty sure the owner took good care of the car. Without this extra protection, you can expect to replace the crash bar and repair the rockers several times over the life of the car. WARNING: It won’t stop all scraping damage, just reduce the possibility of it happening, and reduce the damage when it does happen. Low hanging headers will probably still scrape. Hood seal weatherstrip The sides and back of the hood compartment have weather-strip installed from the factory. The front is left open. Many owners install weather-strip along this front edge. You may not even notice it since it looks identical to rest of the weather-stripping. This extra weather-strip helps keep the engine compartment clean, and may also help the air intake system work better. This is another sign that the owner took good care of the car. The engine compartment stays pretty clean, but this the "extra step". A/C System There are two kinds of climate controls. One is manual with knobs, and the other is a dual-zone electronic system. The dual-zone system did cost more, but is not as reliable as the manual system. A leaking battery can affect both systems; a symptom is when the vents cannot be switched. Over time, and especially in humid climates, condensation can leak onto the passenger side carpet. There are 3 udders under the driver’s side cowl, and behind the battery. There are slits on the bottom--vigorously squeeze and massage the udders until free of debris. If the vent settings cannot be changed, the vacuum line is probably loose, clogged or broken. Read more! Squeaky steering wheel When you turn the steering wheel, you may hear a squeak. It's just the plastic surfaces rubbing against each other. A shot of lubricant fixes this. Squeaky/chirping/grinding wheel bearings Drive slowly, better yet, coast along at low speeds with the windows open in a quiet location. Listen for a squeak from the wheels. Try turning in different directions. If you hear the rear wheels squeaking, you may have a worn wheel bearing. A replacement bearing costs $600 list, but you can usually find it for $400-450. I've heard that AutoZone has a better replacement for $126 by a company named Timken. The part is easy to replace if you can separate the ball joints; I bought the Kent-Moore tool to do mine. The problem may persist safely for a few months, but eventually will become annoying. It seems to be a common problem, and more so for the rear wheel bearing. I've never heard of it happening twice to the same car, so if you fix it once, you're probably good for life. Several racers replace their wheel bearings every year.
Here's the Kent-More ball joint breaker:
 A broken emergency drum clip may cause a false diagnosis. See the section on the parking brakes, and be careful when removing & replacing the rear rotors. Oil woes Many late 2000 thru 2001 Vette's burn a lot of oil when the engine is kept constantly over 4,000 rpm's. This is caused by ring flutter, which allows extra oil to seep past the oil control rings, but doesn't seem to cause any extra wear to the engine. Chevrolet has rebuilt and replaced engines for owners that complained about excessive oil consumption. Their policy is that while the engine isn't normally operated like that outside of racing, it is the owner's prerogative to drive around in second gear all the time if they want to. It is covered under the warranty. The PCV system also has a tendency to suck oil back into the intake at high rpm's. It doesn't seem to cause any problems, other than a slight mess inside the intake manifold. The newer style PCV system can be installed, but this requires removing all the components in the top of the engine valley. Usually only racer's bother with the hassle. Several generations of PCV systems have had the problem, and at this time, December 2004, the PCV system still sucks oil into the intake. The oil-sucking problem will cause carbon buildup in the cylinders. The dealership sells GM Top End Cleaner, and Napa sells SeaFoam. The Top End Cleaner is not available in some smog states like California. Run a tube from the bottle into the hole for the PCV system behind the throttle body on the passenger side. Start the car, then start slowly sucking the solution into the engine. Don’t go too fast or the engine could lockup. As soon as the solution is gone, stop the motor for >4 hours, but preferably 12 hours. Be aware that when the engine is restarted, there will be a LOT of smoke! The oil-sucking can be prevented by installing a catch can. AMW and Greddy make catch cans, but a homebuilt catch can may be built using a Campbell-Hausfield air tool oil separator from most tool stores, including AutoZone. The AMW and Greddy cans are ~$100, but look great. The CH can is $15-25 for all the parts, and you can see how much oil is in it. Overheating & burning smells Even though the engine can heat up to 220, even 240 degrees Fahrenheit, this is normal. The radiator will keep the engine cool enough unless the radiator is blocked. Reprogramming the PCM can allow the fans to turn on earlier. If the fans also cool an aftermarket oil cooler, make sure the oil occasionally gets to 220 degrees to allow condensation and fuel to evaporate away. Fan settings and oil thermostats are two different ways to do this. It's not uncommon for plastic bags to get sucked up under the front bumper, and cover the radiator, thus causing the car to truly overheat. If this happens, take a quick peek under the bumper, and remove anything under there. Sometimes bags get stuck to the exhaust pipes too, causing quite a stench as they burn away. If an aftermarket oil cooler is installed, take extra care to keep the oil lines away from the exhaust pipes. They may last for years before failing, but they will eventually fail. The best protection is space, and for extra insurance, put heat wrap around the oil lines and ceramic coat the exhaust pipes. Locked steering column All C5’s, particularly manual transmission C5’s, and early C6 steering columns have a tendency to lock and stay locked. Usually it can be unlocked once, but just once. Some owners claim that vigorously shaking the steering wheel can unlock the steering wheel. Dealer's are able to disable the locking mechanism with a modified locking plate. Currently this is the only real method to disable the locking mechanism. Basically the wheel will still try to lock, but there will be nothing for it to lock to. It’s like a door dead bolt with a slot cut into the door jamb. There is a $100 kit that disables the steering column lock, and can be installed easily, but enough car vibrations can cause the lock to fall into the locking plate, even while driving! GM has a part (#88952428 or 88952428) that has a harness wiring jumper and different lock plate. Not sure what the difference in the kits are. After reading a few posts, manual transmission C5’s & C6’s are still in danger, even if the lock is disabled. The lock can vibrate out over time and get trapped in the locking plate. Auto transmission cars that have undergone the recall and new auto’s will not have the locking plate at all, so they are safe. More information about COMPLETELY disabling the steering column lock will be forthcoming from other’s on the forum, and by my own personal project. Until then, here are a few links about the topic: Column Lock Harness K Installation A4 non locking column plate --- must be a member Column-lock again even with CLB! Has anyone ELSE beat column lock? Faulty gas gauge If you have bad gas (phew!), the fuel sender can be affected by the high sulfur content in the fuel, and cause the gauge to read empty. They car will still operate normally, and the gas gauge will work again if you use better gas, and will usually start again when you restart the car. It's just better to use good gas. Some people have had luck with running fuel filter cleaners thru the gas tank. New fuel senders sometimes fixes this problem. This thread has a LOT of ideas about what could be causing the problems, how to avoid problems, and how to fix it. It also points out how the late C5 fuel tanks and crossover tube is different. Noisy fuel pump There are two fuel tanks, and two fuel pumps. One fuel pump continually pumps gas from the passenger side tank into the driver side tank, and is quiet. The main fuel pump is directly behind the drivers seat, and can be annoying loud, especially on early C5’s. It's normal, and not a sign of a failing fuel pump. Chevrolet does have a bulletin out instructing how to better insulate against the sound of the fuel pump. This is merely an annoyance. A newer, quieter pump can also be installed. Extremely high oil pressure reading The oil pressure sensor can fail, but it is still okay to drive. Turn the car off, but with the key in the “on” position and check the oil pressure gauge. It should read “0”. If the oil pressure sensor is bad, it will show a positive reading. The oil pressure sender is located behind the intake manifold, and will require moving the intake manifold. The sender costs about $40 and part # 12573107 or 12562230. How-to Suspension squeaking In cold weather you may hear the suspension creak when you go over speed bumps. To fix this, clean (optional) and lubricate the sway bar bushings. The adjustable metal sway bar end links on Hotchkis and T1 bars can also create loud clicking sounds. Double check the alignment. The goal is to get the "eyes" as centered as possible on both ends of the endlink as the suspension moves.
Notice how in the picture below teh "eyes" are aligned? This
configuration "clicked" on the front swaybar until I lengthened the endlinks a
few rounds and rotated one end of the link by ~25 degrees.
Most adjustable end links are quiet initially, but wear out and get noisy over
time. Greasing and protecting the end links from dirt may prevent wear.
I've installed zerk grease fittings to make it possible to grease the swaybar
bushings without having to remove them.
Tough shifting The shifter in manually shifted Corvette's takes a strong arm to get it into gear. You really have to make sure that the shifter is fully in 1st and Reverse, or it will pop out of gear when you let the clutch out. This is not the fault of the car, but the fault of the driver. Manual transmissions -- Replacing the transmission fluid often helps shifting. Early transmissions have paper blocker ring that require Dexron III compatible (usually organic) fluid because some synthetics will destroy the paper blocker rings and subsequently the transmission. Later transmissions, and all rebuilt transmissions, have Kevlar/carbon fiber parts that allow the use of synthetic fluids. I believe the 98-00 transmissions have the paper blocker rings. The safe transmission fluids seem to be: GM Synchromesh PN #12345349, Honda ATF-Z1, Royal Purple Synchromax, Amsoil ATF, O’Reilly Dexron III ATF. The following transmission fluids may be unsafe for early transmissions: Redline D4 ATF, Mobil 1 ATF, Royal Purple Max ATF. Related threads: LS1.com - Ending the speculation: Blocker rings, who's had them fail? LS1Tech.com - Ending the speculation: Blocker rings, who's had them fail? Mobil 1 Synthetic ATF for a M6? If it is especially tough to shift into 2nd or 4th gear, it's possible that the synchro's are worn out or the forks are bent. Do NOT force it into gear. Abuse creates and aggravates this problem. You can still drive, even quite well, without synchro's....or a clutch for that matter if you know how to rev match. Some aftermarket shifters make it easier to make sure you're fully in gear, and prevent gear grinding, but they also vibrate, and require more effort to shift. The stock shifter has a tuned weight damper that changes the vibrations to a non-audible frequency. The shaking doesn’t annoy some people, and there are some fixes. Leaky butt The differential can leak from the side covers. The problem has to do with the design. The lip on the casing is not wide enough to create a proper seal with the cover. Resealing the covers can be successful, but many dealers do not use the correct sealant. Inside/outside tire spinning If one tire spins while turning, adjust the friction modifier ratio. Aftermarket gear fluid from Royal Purple, Amsoil and Redline do not require additional friction modifier. GM’s friction modifier is PN #12377916. Too much friction modifier and the inside tire will spin/skip/hop. Too little friction modifier and the outside tire will spin/skip/hop. -- Thanks Russ! Tire hop Tire hop during hard acceleration in cold weather is common, even if the same tires don’t hop in warmer weather. Tire rubber when viewed thru a microscope looks like a web. Normally parts of this web grabs onto objects on the ground and stretch until either the car moves forward, or the web breaks, resulting in tire spin. I believe in cold weather, the web is too stiff for either of these events to occur, so the tires hop. To find out more, read Racing & High Performance Tire: Using Tires to Tune for Grip and Balance. I haven’t read it, but if you do, please let me know if my guess is correct. I found a couple stories on Google about people curing wheel hop with stiffer bushings and/or (jounce) shocks. Interior rattles The visors may rattle when they are put up, but if you flip them down, the rattle goes away. Squeezing the mirror lid down seems to take care of it. Try glueing a piece of felt or velcro between the mirror and lid to see if that fixes it. Caravaggio also makes replacement leather visors, but they go for $400. The stereo is Bose, and to go along with the historically crappy build quality of Bose products, Bose has graced the Corvette with Bose emblems on the door speaker covers that rattle when you play music with bass. A Bose system doesn't exist that puts out good bass, but the system still manages to rattle the emblems when playing Country, Hip Hop, or Techno at moderate volumes. Check this problem by having a passenger and yourself putting a finger on the emblems with music playing. Glue the emblems down to fix it. If the roof isn't tightened down enough, it will rattle. There are some adjustment screws in the roof to make this adjustment. Belt Chirping During cold weather, the belt can chirp. Goodyear Gatorback belts from AutoZone don’t chirp. Sticky Hatch During cold weather, the hatch may pop up slowly, or not at all. Spray the latches with silicone grease until they come up properly. If the struts do not hold up the hatch, try lubing the strut bars. 1997: Service Bulletin: Hatch Will Not Pop Up When Activated in Cold Weather Rocker failure The needle bearings in the OEM rockers have been known to fail. Usually the problem is noticed with extra valvetrain noise and needle bearings stuck to a magnetic oil plug. Nasty Performance will rebuild OEM rockers with Harland Sharp bearings. This seems to be one of the better solutions since the stock rocker is very good at high rpms. Most aftermarket rockers are nose heavy and require grinding the heads and valve covers to fit. Currently Harland Sharp rockers are having problems with c-clip retainers falling off and causing problems on the way. I’ll be following this issue since I have a set of HS rockers on my shelf waiting for this issue to be resolved. Here are some links: LS1Tech - EMERGENCY!! ROCKERS! Help ASAP! LS1Tech - Harland Sharp Rocker Failure LS1Tech - Install or not install HS rockers? 1998-2002: Service Bulletin: Needle Bearings Found In Oil Pan (Replace Rocker Arms) Other Information Active Stability Control This allows you to keep some control of the car even when you do really stupid stunts. It doesn't bend the laws of physics, but will keep the car pointed where you are steering; you may still slide off the road, but at least the car will be pointed in the direction you were steering! One of the sensors is located around the passenger seat, and needs to be considered when installing a racing bucket. If you move that sensor, Active Stability will not know how to balance the car, and can be very dangerous. Active Stability came out around '99. Jacking The C5 was the first car to use hydroformed frame rails. Hydroformed rails are quickly becoming a common platform for new cars, but not many shops are prepared to lift these vehicles. The C5 requires an adapter for regular jacks and lifts to fit the jacking points. Make your own adapters with a hockey puck (or two) with a 1 1/2" eye bolt screwed thru the center. Stick the eye bolt thru the slit in the jacking point, turn 90 degrees, place jack under adapter and jack away....if you can get the jack under the car. You may have to use ramps. The C5 is so low that most people make their own wooden ramps....rhino ramps are too steep. Key Fobs There are basically two different kinds of key fobs, and they are not compatible with each other. 97-00, but 00 does not have the Passive Lock feature 01-04 Both remotes use a CR2450 coin type battery. I found replacement batteries at Office Depot. To replace, use a coin to wedge between the seam, and twist. Ref: Service manual, page 8-747.

Spark plugs The OEM platinum plugs, along with other plugs have had problems with the pucks falling off. I have a picture of missing pucks in this thread. This thread outlines some of the problems with using platinum, and a recommendation for using silver tipped plugs by Beru. Basically, of all spark plug tips, platinum is the worst conductor, copper is good, iridium is even better and silver is the best. Don’t take my word for it, do a little research, starting with this review. As for longevity, platinum, iridium and silver do have an advantage over copper, but plugs foul up after ~10K miles, negating any difference corrosion would cause, and no plug will run well after 100K miles. The best way to go for most people are inexpensive TR-55 copper spark plugs. To make the spark plugs easier to change, get the Snap-On double-swivel sparkplug tool and remove the coil packs.

Aerodynamics, gearing and top speed
The hardtops and Z06 have shorter rear windows, are less aerodynamic, noisier, and weigh less than the standard C5 couple like mine. Even though the Z06 has more hp than standard C5’s, they have a lower top speed than manual Z51 C5 coupes. This is due to both aerodynamics and gearing. All C5’s top out at redline in 5th gear, so a taller 5th gear, or much shorter 6th gear, or taller redline is required to go faster. All else being equal, a Z51 coupe will still go faster than a Z06.
Above 175 mph, the aerodynamic limits of the C5 are nearly reached, and the
car starts to become unstable. Air builds up under the front of the car,
and with no real place to escape, front end lift occurs, making it difficult
to keep the car in a smooth straight line, especially if the road has the
slightest waviness. This can be solved with a vented hood like the ACP C5-R or
MCM vented hoods. The ACP and Motor City hoods both have a center vent,
but the ACP also have vents above the wheel wells, which if used, would reduce
lift further, and allow greater cooling for the brakes.
Weight reduction You can achieve substantial weight reduction with the following modifications, while still having a car that's very comfortable to drive. Most of these modifications will directly increase (and decrease in a few cases) the safety of the car, while safety is indirectly improved due to the better handling and limits of a lighter car. Fighter pilots say "speed is life". Acceleration, deceleration, and lateral acceleration are all forms of acceleration, and lighter cars accelerate better in each of these ways because the tires have less mass to control....thus a lighter car is a safer car. Lighter cars have better moments of inertia which allows them to turn in more easily and roll less. Lighter cars are also easier on the tires and gas. All the stage weight estimates are typically wild butt guesses, but it makes it easy to see what is possible. The weight listings in the separate weight posting is MUCH more reliable.

The forward leg of the control arm is set near to wheel center. The forward leg of the lower control arms is fitted with a "handling" bushing; the rear leg is fitted with a "ride" bushing. The "ride" bushing absorbs the brunt of road deflections while the "handling" bushing absorbs the brunt of the cornering forces. The "handling" bushing is 3-6 times stiffer than the "ride" bushing.

The tunnel closeout (aka tunnel plate) increased 1st structure torsion mode by ~2 Hz. It makes sense that stronger tunnel plates stiffen the chassis. The C6 Z06 has carbon fiber floorboards to reduce weight, but possibly stiffen the chassis as well. The boards behind the seats often flex and pop on convertibles, and I believe stiffer boards would further increase chassis stiffness.
