1. Go to tirerack.com
2. Select "wheels"
3. When asked for model, select BMW
4. Year - 2005
5. Make 330 Coupe, Performance Pkg.
6. Select 18" Diamater on filter bar on the side.
7. Browse through over 220 Wheels that will fit the GTO (at least as far as the bolt pattern is concerned...just watch your offset/backspacing).
I like the ASA Wheels (decent price, looks and weight). You can get staggered set-ups that should fit (or be close enough if you have a suspension upgrade/fender roll/etc.). The ASA GT5 wheels can be purchased in the following 18" dia. config.:
The rubber that the suggest for the wheels is probably going to be more narrow than you will run, so buy wheels under a new search. (The recommend 225mm for the fronts and 255mm for the rear).
Happy hunting. Hope this helped.
