Bill 97SE:
I got the same ASA wheels from tire rack 2 months ago. You're gonna like 'em!
I got the 17 x 7.5 with Sumotomo 215-45-17 tires.
The wheels come with a hub centric ring, use them, they're already installed. I did not remove the rotor retaining nuts, maybe I should have. Balance seems to be perfect.
