BBP conversion

you realize that the Dr. Diff set up is factory brakes, right?

14" factory steel bbp rims fit the smaller 11" rotor, because that's how ma mopar made them.

Yup, just 73+ Ma Mopar disks.

I will say though that there are some 14” wheels that don’t fit. I don’t have a definitive list or anything, but some 14” wheels work and some don’t. Especially if you’re getting the kit that has the 5x4” pattern on the later rotors and trying to use SBP 14” wheels.
