which gt rims?

 

the once you have on your car in this picture. wheels/tires that can be purchased from Saleen Take Off parts site.

 

get some headers in there...it would be better than the driveshaft...more torque...

 

headers are minimal gain, you would definately see more gains from a lightweight 1 piece driveshaft.

 

but those driveshafts are pretty expensive..

 

Actually, a custom drive-shaft is not that expensive. I ordered one from a place in Texas for about $350. It's about 30% lighter than the stock shaft despite still being a steel shaft but it's much stronger that the stock one. The stock drive-shaft on our cars are technically one piece drive-shafts, slip in tube, whereas the GT's are actual two pice drive-shafts. I'll be getting mine in next week and hopefully will get it installed by the weekend.
