there is a reason the GS-T is FWD.. I dont think you have the money or knowledge required to make it RWD. upkeep for it would be a bitch too. goodluck. blake fuller made his integra rwd and it cost like 1000000$ so have fun with that. or just learn to slide a FWD car, scandanavian flick ftw!!

heres some pointers.
