The setup i was getting fabricated is for a 15" wheel...has between an 1/8" to a 1/4" of clearance and sometimes you have to take a grinder to part of the caliper to get it to clear the wheel weights....anyways, it's a 12" rotor, still 2 inches larger than the stock, but I'm not liking how small it looks in a 16" wheel...
Of course, 1 week before the mountain run and i wanna change it all! I can shim the brackets to bring the caliper out but having to look for a larger rotor now...spent most of the day trying to figure out clearances and how big i can go. Thinking about a 13" rotor...i can always keep a spare 12" around and simply remove the shims to fit a 15" wheel w/ slicks for track days...
