That might not be true. Looks like the MB bolt pattern is 5x112 and if the hole is big enough, a 1/2" stud on a 5x4.5/114.3 pattern might just slide in. The rotor I looked up showed a 0.6"/15.3mm diameter stud hole and a quick AutoCAD layout says it should just fit.

This is correct. I have the MB CL500 rotors as part of the Stage 4 kit, they fit without any redrilling. I spoke to Cass about that because I like to know what the options are for replacements.

The 13” MB rotor is nicer in that respect than the 13” C4 rotor used with the stage 3 kit, because that rotor has to be redrilled to work (Cass orders blank C4 rotors and has them drilled). The CL500 rotor for the stage 4 kit can be bought off the shelf from anywhere and works out of the box.

Either way the 18’s have much better clearance

This is news for me. Is Cass Dr Diff? I could have sworn I asked him about them and he said the ones he supplies are re-drilled. if they fit off the shelf then I think that is probably the best option because they have the smaller Diameter and the thicker width.
