Sounds good, but if you want faster accelleration as well as "bling" factor, 16" rims are the way to go.
Everything else sounds like you're on the right track.
Oh, if you really want "go" then ditch the body kit as well. (Can you tell I'm a fan of sleepers???) Body kits sometimes do look REALLY good, but they can also look REALLY bad and with all the weight they add, I don't find them to have quite the bang for the buck. I'm just anti-kit, though, so do your own thing. Can't wait to see pics!
