Weren't those Challenger Scat Pack rear rotors? Those are 13.78" (350mm).

I think some of the SP and Hellcat guys are able to run 17" wheels over those rotors, so they might fit?

I should add that my front brake setup is 13" Cobra rotors and C5 vette calipers and just barely fit my 17" wheels. No way a bigger rotor would fit a 17" wheel with these calipers. So the calipers you run have a huge impact.

I run hubs I purchased from Bergman Auto Craft. They may be the same hubs that DrDiff used to offer. I run GEN III Viper Brembo calipers with the SRT 14.1" rotor. The Enkei PR01 (18x9 +35) wheels would not clear the hubs. I found a small local machine shop that was kind enough to machine down the hubs to clear the wheels. There is no way a 17" wheel will clear the calipers on this setup. You MAY try a 13.3" rotor with a 17". I run a 255/40-18 Michelin that is 26" tall. Hope these pictures help.
