Thought this topic came up already but I drew a blank on my search. Anyway, anybody measure up clearance on the cup wheels for max disc size + calipers? theoretically the standard 280mm discs (28mm wide pls confirm) could be uprated to 300mm or so. I also tried finding some 4 pot calipers that could fit the standard 280mm discs, but had some problems finding a caliper to fit 28mm thick discs in that size ??
