Rear Wilwood rear brakes
Well I just went ahead and carefully profiled the calipers for .090" clearance.
The Wilwood unlike a Strange is is not fully machinde in that area and has excessive material on the casting. The two halves of the calipers where they bolt together are not even close to same size. There is still adequate material now. Just a shame they don't engineer close tolerances than that. Hate to have to customize on a safety item.
