Loads of pics of aftermarket alloys on here. Unless you like big wheels a set of 16's will be fine.
I'd look at oz, team dynamics etc & get a package. I'd stay away from wolfrace unless you get a nice set from them, as most of theirs are plain cheap & nasty.
An alternative would be to get a set of turini's for it.
Or a set of 172 or 182 alloys (will be about half the price of your budget)
