I just wanted to give a heads up to any 818R builders or 818S Trackers-
I ordered 2 sets of Team Dynamics Pro Race 1.2's. I went with 17x8 Et+40 front and 17x9 Et+40 rear.
I wish I ordered them sooner, because it is a 6-8 week wait (Custom made in Europe). So keep that in mind if you want strong racing wheels to order before your build starts! :P. The price is good also.
I have personal experience with these wheels on the track, and they can take any abuse I could muster. If you watch the British Touring Car series, these are the wheels they use. I think they look great also.
