They are Baer. I bought them from Cass (Dr Diff), I do not know the part number. He sold me matching rear rotors also, I think the rears are off the shelf Mustang Cobra application.
Interesting. You must have gotten an older kit. I got redrilled Mercedes rotors and (God Forbid) Cass goes out of business, I'd rather not order a set of Mercedes rotors and send them to a machine shop to get them re-drilled. If you ever get the chance to find the part numbers on them from bear, can you pm them them to me please?
