Shaving wheels to clear calipers
Anybody ever try to mill or "turn" wheels to take material off the inside of the spokes. Just attempted to install a Stoptech BBK and have approx. .5mm clearance which isn't enough. I'd prefer not to run a spacer since my 35mm offset wheels are at my personal limit already. I did print out the template and it appeared I had about 2mm clearance, but I guess not. I'd just have to take 2mm off the ridges (extra material cast on the inside edges of the spokes) on the inside of the spokes. I know these ridges provide strength for the wheel, but 2 mm would still leave approx. 3 mm of the ridge remaining. I do track my car so I'm am concerned over high stresses, but you have to figure wheels have a design safety factor of about 2. Inputs?

I really doubt a wheel maker would design their wheel on that ragged of an edge where a mm would make a big diff. But you would be hardpressed to find someone to actually recommend it.
Another idea is to take 1 mm off the caliper and 1mm off the spoke.
Or as someone else suggested a spacer. I'd take a commonly available 5 mm spacer and have a machine shop mill it down to 2-3mm. That's probably what I'd do

Thanks for re-enforcing what I think I already knew. Shaving 1mm off the wheel and 1mm off the corners of the caliper would be ideal but a pain. I'm not even sure I could find someone to do the wheels and if I did shave the calipers, I'd have to re-paint them. Getting a 2mm spacer (or milling a 5mm down) is the most logical and I'll just have to get used to the wheels sticking out farther.

Sell your wheels and buy new wheels that fit.
