Car looks clean man. I like you suspension setup. If you can find a sedan front bumper lip, side skirts and a rear lip that would look hot too besides the MSP kit.
I'm doing it too, I'm just shooting for a reasonable 240 whp and not 300+.
I have some aftermarkets from autozone installed behind the center grill, but i'd much rather have the stock ones as it makes the front look so much cleaner!
