So I don’t have a picture of the rotor by itself on the hub but the Stage 4 rotors are not redrilled at all. They fit tight, so you do have to make sure they seat all the down on the hub, but they don’t need any opening up of the lug holes. With this size picture I’m not sure it will be obvious but in the original and of course in person it’s obvious that nothing is done to the CL500 rotors. The stage 3 rotors on the right are clearly redrilled from 5x4.75”

Not sure who this is directed at, but I haven’t had any issues with brake or suspension components either, everything from Cass at DoctorDiff has fit and worked exactly as advertised.
It’s not like BAC sells parts that are all from the same manufacturer or vehicle.
