Dr Diff 13" PBR kit and Year one 17" rallye wheels

I did a search couldn't find an answer. Will the Year One 17" rallye wheels fit over the Dr Diff 13" PBR brake kit?

Which style? Cobra-style or Brembo-style? I mocked up a 17" Mustang wheel on my 13" Brembo-style disc kit and the caliper rubbed the inside diameter of the wheel. FWIW, those calipers are huge in length and width.

I spoke with Cass about this a year or two ago and he said they will not work.

The PBR is the 2 piston. The brembo is a fixed 4 piston.

Year One wheels will not fit my Stage 4 (Brembo style) brake kit.

I think they will fit my Stage 3 (PBR style) kit, but I don't know for sure.

have dr. diff(cass) old 13" viper kit and they do not fit. I even shaved off 3/16" off the caliper bracket and they still hit, I could have grounded the calipers a bit on the top side, or shaved more off the caliper bracket and got the rotors cut smaller but i did not wanna do this.

Yea I have read a lot of your posts.
