How open would that group be in me joining and asking if there’s interest? Or…you could point them to this thread if you’d like. I’d be happy to answer any/all questions in regards to the rotors.
Yeah not sure why Audi felt the need, in this one instance, to use a unique size. I thought for sure it’d be the same rotor as say the RS6 or S6 iron rotor but it’s completely unique in diameter and width.
They could have even carried on with the B8’s 19Z caliper and CCB rotor. The new RS3 is using that caliper and assuming the same rotor (380x38mm) for it’s CCB setup.
