Unless you're willing to cut, glass and bond various bits of plastic to make a custom kit, i really wouldn't bother. These cheapo 'different' looking bodykits you see on ebay are a load of gash, poor quality.. and even poorer taste. People will point and laugh as you drive by.
Maybe try getting some old mk4 bumpers from a scrapyard.. and try your hand at smoothing the creases/rubbing strips out.. get them colour coded and stick them on.
My favourite replica wheels at the moment are RS6 reps.. big fat 5 spokes.
