another option would be to throw $20k at jeff and buy his limited edition 06 spec c with 1000k's on it then strip your car to a shell and replace EVERYTHING .... this will give you a bulletproof package that goes hard, stops hard and everything in between, then sell all your standard stuff to re-coup some of the cost
