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.

Yes, Cass is Dr. Diff. Not saying he doesn't redrill them, I wouldn't be surprised that people complain if they have to carefully slip them on. And tolerances might be that 4 out of 5 fit and one doesn't and by redrilling them he doesn't run the risk of someone posting bad comments on the internet. Could be he just hits them with a 5/8" bit to make sure they are opened up enough, too. Not sure. And Blu said he talked to Cass and that they aren't redrilled, so there is that too.

I'm just saying if the specs match reality, they should be very close to slipping right on. I would buy one locally and try it. If it doesn't work, returns are easy.

Hmm...something else I just thought of. If the knurl on the stud sticks out past the hub face, it could cause the rotor not to seat. I was only looking at the stud itself.

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”

I didn't have any problems with brake components or suspension because I bought everything from Bergman Auto Craft. Just saying...

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.

And that’s by no means a dig on Peter or BAC, I run plenty of parts from him and they’re awesome. But whether you buy everything from BAC, or buy stuff from BAC, DoctorDiff, Summit etc you’re getting parts from different manufacturers.
