as has already been eluded to, it's not easy to take weight out of these cars without sacraficing comfort or driveability.

The very first place I would start is with the factory running stock. Per my bathroom scale (I know, not the most accurate) each rear wheel and run-flat tire weighs in around 65lbs.

A nice set of forged wheels and non-runflat tires might possibly shed upwards of 20lbs from each corner while also providing better grip and handling than the run-craps.

That's close to 100 lbs at that point and all rotational mass as well which will provide the greatest weight savings benefit.

Next I'd go to a lightweight hood and battery. This will shave slightly more weight, but probably not a measurable amount.

Something else to consider is the front glass. Don't quote me on this, but I think that the Z06 windshield is a thinner piece specifically for the weight savings. Again, I may be wrong here, but that would also be a direction I would look if you are serious about weight savings.

They are big bucks, but you could also swap to a 2 piece rotor. This is probably going to save another 5-10 lbs per wheel.

Again, expense is a factor, but you can switch to a lightweight flywheel, and pressure plate, as well as a carbon driveline.

Outside of that, you start getting rid of items that are there for comfort and convienence, which can start effecting drive quality.

Why not?? 24LBS is a lot for a 1pc object and its by far the easist to remove without mutilating your car...Besides it makes your car 24LBS less top heavy.

Depending on what type of driving and or racing you are doing however, the aerodynamic losses might overcome any weight savings gained.

True.
But on the drag strip (if they'd even let you run open top) the aerodynamic drag will slow ya down more than the weight savings will give ya.

Does anyone know what the weight difference is between the 2008 factory wheels? I've read that people think that the QX7 forged wheels are lighter. Has anyone weighed them? compared to the split spoke, the QX3's ,and the stock 07 wheel?

TIA

Lets start a list of things we know:

24lbs Tires stock(f29/r35) PS2(f24/r28) = -24lbs or -34 for ET streets
(you can save 10 more by going to ET streets(22lbs) on the rear)

Can anyone comfirm:
10-15 Headers
10-15 Xpipe (no cats)
15-17 Battery
10-20 Wheels
2- 5 Top swap
1- 2 TPS sensors

Fuel rail covers and the under-hood insulation mat.

Minimal savings, but things that really aren't needed and won't affect much.

Battery relocation doesn't typically reduce weight (it can actually add weight due the added length of cables and wiring) but it does help shift it back which helps in drag racing, road racing and safety.
A lightweight battery (I had one in my Z28 for a while) in the stock location can save up to 22 pounds off the nose alone.

Lightweight seats and/or removal of passenger seat.
Magnesium or carbon fiber rims (skinny ones up front if drag racing)
Non runflat tires
Remove front sway bar (again for drag racing duty only)
Titanium exhaust (or none at all)
Carbon fiber hood and other body panels
Lexan windows
Removing the air bags and stereo system (along with the A/C and carpets/sound deadening mentioned above)

It will not be easy (nor inexpensive ) to get the car down to 2800 pounds without really cutting it up but it is possible.
i saw one the other day at the wrecking yard it was just the engine/ trany. frame and wheels, with a seat thats what you need!

More HP doesn't make up for more weight... Reduce the mass for best handling, dynamics and speed.

But not on a C6..Mustangs and firebirds fit this criteria mod..

Heffers need this mod diet, not a perfectly designed C6 that weighs what 3,200 lbs? This is a classic car, weight reduction only yields minor performance enhancements when it comes to the C6. If you planning to strictly track the car, then go for it with that plexan crap and insulation removal, every 100lbs is only a .1 tenth in the 1/4.

I would not gut a C6 unless it's the test bed for an aftermarket company, and that you are compensated fairly for your ungodly sacrifice..
