Yeah, I understand what you're saying. The extra outside thickness may create too much of a clearance problem for the wilwoods with the brembos if offset is different.

The thing I was thinking is that if the offset was the same as stock, and there are brackets that make the wilwood dynalites work with stock rotors and 300mm, then the only difference would be the rotor thickness. Since the calipers can handle 1.1" thick rotors that doesn't change anything. The centerline of the rotor would remain the same. So all the new bracket would do is move the caliper up and not out keeping the same centerline. Depending on the wheel design of course, clearance should be fine with the caliper about one inch higher.

Is my logic wrong on this? Maybe the brembos have a different offset then stock rotors.
