What could be done to further reduce the weight of a GS? Not saying i would just wondering if it would be easy or expensive to shave a 100 pounds or so off. I know the easiest way to reduce the weight is carbon fiber sides and such. Anything else that can been cut back?

thanks, Brett

 

Put only three gallons of gas in the tank and save something like 105 lbs or so.

 

Other than running light on fuel it depends how much you want to modify or gut your new car (if at all). Hanging-out with Corvette road racers I've seen all kinds of weight reducing modifications from totally gutted Corvettes with full fiberglass/carbon fiber body shells and everything in-between.

My closest C6 racing friend has a highly modified C6 and just did some things to reduce weight. He replaced the hood...drilled or 'louvered' it to lighten weight and vent heat; removed most of the interior carpeting and insulation; replaced both side doors with 'shell' doors (no glass and the support structure was drilled-out wherever possible); removed the passenger seat; replaced the driver's seat with a lighter weight racing seat; replaced and lightened the rear hatch using lexan instead of glass. I'm guessing he'll replace the windshield with lexan soon. The good thing is he can put the stock seats, hood, hatch and doors back on in about day if he wants.

A simple thing that saves a little weight is to remove your window washing reservoir. You could go to lighter weight wheels. I wouldn't do it but you could replace the OEM battery with a light weight 'racing' battery. Any weight reduction helps but to achieve anything significant IMO involves making some real changes. As always...don't take a passenger with you. Good luck!

 

Replace the front fenders with Z06 fenders

 

very expensive to shave 100 pounds.

Z06/ZR1 front fenders would shave 26.5# and the wheelhouses would shave another 3.23# but very difficult(re: expensive) to change out.

Replacing the aluminum front engine cradle with the Z06/ZR1 Mg would shave 10.1#.

Replacing the propshaft withan aftermarket CF unit would shave 4.57#.

The ZR1 CF roof bow and roof panel would shave 7.7#.

If you did the above you would get ~49# reduction.

A hand crafted titanium exhaust system would get you another 18#(super expensive)

or you could marry a 95# woman and let her do all the driving(alone) and see the 100# reduction you are looking for.

 

Don't forget the driver weight.

I just couldn't resist.

 

Replace it with a '08, or '09 1LT, MZ6, Z51, NPP, QX1 coupe.
