Default Weight reduction..?

Hello everyone
i bought my 08 base model 2-3 weeks ago and I’ve been enjoying it greatly (except the myriad of malfunctions, but whatevs)
I just now ran the VIN and see the curb weight is 3217lbs.
that seems high to me. For a sports car.

while it’s performance is spectacular; I cant shake the idea of weight reduction. I searched the forum and didn’t find anything.
Does anyone know of weight reduction ideas for C6 corvette?

Fill the tires with helium.

Meaning, 3.2k is light, relatively speaking. If you get right numbers for weights, they have crept up into serious heavyness.

Personally I always wonder, in our case (C6's), how much weight does the ACP carbon body save ? Is it a hundred or greater ?

I've looked into this topic as well, search for weight savings on the internet, you'll see standard hot rod practices work, i.e. lithium battery for instance

Plenty of threads on here talking about weight reduction, especially in the racing forums. Though, 3,200 is most definitely light for a sports car.

It is less than
Viper : 3,400
GTR : 3.800
Supra : 3.400

Same weight as a McLaren 720s

Just about all sports cars, both exotic and domestic with V6 or V8 power are comparable to the C6 curb weight. To answer the question a few ideas would be to replace the exhaust system with something lighter, such as headers and minimal mufflers, if any. Lithium battery over the stock lead-acid variety. Gut the interior of unneeded amenities (these would be your choice). Pull off the HVAC system, (who needs A/C?). Replace seats with true sport seats and eliminate the passenger seat. Replace brake rotors with lighter weight 2-piece rotors.

Obviously, you should also maintain your own weight to less than 200lbs, ideally 150-180lbs max.

These are a few ideas to shave off some weight. Or you could replace the C6 with a MX5 and drop about 1000lbs.

Might also be helpful if you could elaborate on what you are attempting to achieve and why?

Good luck and let us know what you are able to accomplish...GD

Start removing interior parts and replacing other stuff with carbon fiber.

3200 pounds is actually quite light by modern standards. Not much lighter than that with any sort of size and power.

FWIW - Not all weight is equal. Pound for pound reducing unsprung weight will pay much greater dividends than reducing sprung weight.

This may be more extreme than what you're looking for but I got my base model car down to 2933lbs by doing the following:
  • Front skinnies
  • Remove AC condenser, condenser and lines
  • Remove all carpet
  • Remove passenger seat
  • Straight pipes instead of my Borla exhaust
  • Remove windshield fluid reservoir
  • Remove speakers, seat belts and recoil mechanism, speaker trim
  • Lighter rims and tires on the back (drag radials)
  • Strange front racing brakes
  • 5lb lightweight motorcycle battery

There is a lot that can be done, all up to what you want. Here is a thread from the race section:

https://www.corvetteforum.com/forums...from-a-c6.html

I've removed just simple things for drag and road track use but keep it good for street. XM module, On star module, floor mats, cargo net, side parts of chin air dam, front license plate, engine covers, bags of foam in front of rear wheels, center and rear speakers, light battery etc etc.

I easily got down to under 3000# for racing, without getting extreme. That included the NHRA legal roll bar and harnesses. It's all in the details and the ability to return it back into a leisure road trip or daily driver car in less than an hour.

Some good replies here thanks.

someone mentioned 5lb motorcycle battery: I’ve never heard of that. Who know more details about that?
a 5lb lead acid battery is probably only 50 cranking amps (estimate/guess) right?

also my car has the wheels with 15 spokes- I dislike the look and also wondering if other wheels would be lighter.
I have many more things to say but not much time to spare.

15 spoke wheels

Who made the wheels? Reproductions can be heavy. You might have to look at the backside of the rim to ID. Some of the lightest batteries are lithium ion. You could shop around at Braille, anti gravity batteries, etc.

Most certainly those are heavy wheels, wise shopping. I believe lightest wheels, worrying about weight, are 1-pc forged monobloc, but you will pay through the nose for them. A good budget bet are flow formed wheels, stronger than regular wheels, lighter as well, good option.

I agree with this, also, because their costs get limited with the budget that they implement..

If you can reduce your weight of wheels, it goes long ways!

Nope, 540 CCA.

This is the exact one I use.

That's awesome, I've implemented Braille batteries, you keep your CCA surprisingly well!
