Swapping bumpers will usually work, colour coded ones will look silly unless they are an exact match for your car. Fit some nice alloy wheels, get a DTM style splitter for the front and some tasteful car stickers.
Bodykits are best fitted by pros with spray booths or it can look aweful. Have you had a peek at our POTN shop (link above) for parts - they have a pretty good range plus they pay us a small percentage of each sale which helps keep this site running.
