bodywork ideas or feedback please

I got a 94 gtp with no rear spoiler (much prefered)
A thought popped into my head about maybe changing the rear clip so as to lessen the amount my rear bumper sticks out. Not sayin it doesnt look good now, just more or less bored and need a good excuse to be spending days at a time in the garage. What I'm trying to figure out is if there are any other cars that may have the ass end im lookin for, what problems im gonna run into and other considerations. If anyone has done custom bodywork on their prix, please share your wisdom. p.s. and I need some damn lowering springs too.

i think the back of the 1994 and earlier gp's use a single unispring in the back. That being the case, finding a lowering unispring is gonna be next to impossible.

Are you trying to go for the "Fast and the Furious" look? and if so, why????
