I was going for super trick magnesium centers on my custom wheels from Keizer Wheels, but got a call today that those centers wont work with the 130mm 4 lug spacing. So I'm going to aluminum centers with steel inserts. 15x7" wheels will still weigh under 11 lbs and best news is I'm saving $$$, cost is down to $250 per wheel now. They threw in a little sponsorship discount for me!
They are putting them together tomorrow and onto UPS this week!
