I bought black Team Dynamics rims with white lettering. I exagerated a little about the lowering of the car. It is lowered 1.5" all around and not 2". I too was going to buy Kosei rims but I thought these because they looked a lot nicer, and they had a lot more choice in offsets. There was one small negative, and that is the plastic hub-centric rings that came with them stuck to the front hubs due to brake heat from the track. I had to pry them off the hubs with a screwdriver.
I will re-install wheels as I came home from the track on my stock wheels and take a few pictures and check the actual clearance between stock caliper and my track wheels.
By the way, with regards R compounds, the latest issue of GRM magazine has a new tire test worth checking out.
How does one post pics for this site? If someone lets me know, I will post a couple.
