I reckon before you get a sway bar burn those chrome floor matt's. If its your thang and you like them then keep em. but seriously, i cant stand chrome floor matts.

And yeah, max 16" rims mate. Having a cannon and a stock exhaust is like having huge ball's and a small c*ck IMO. It's not only looks that make your car ricey, its also sounds. Like having a slow as car and putting a huge muffler on it, best example is when i see gli lancers with huge cannon's. Or having a massive sub and cranking it way more than necessary whilst cruising through a shopping centre on a thursday night. Just read up here on OH mate, youll get heaps of good advise
