You running doubles Jeff? What rear Brakes are you using? I'm looking at getting the Mac Fab Doubles and my rear Wilwood brakes need 7.03 min radius. The Mac Fab ring is 6 3/4" inside radius (13 1/2" dia.).
Doubles with Wilwood brakes. Can't say enough good things about the service from Tommy Kirk's crew. Fast turnaround, and they wheels looked perfect when I got them back.
