The high end cars all use Brembo as their caliper supplier. Merc, Porsche, Ferrari, etc.

The next rung down is the pony cars and they basically all use PRB brakes. Some of the really powerful pony cars upgrade to Brembo stuff on special editions or race packages.

There are various Mopar kits available that use either PBR or Brembo calipers. My Viper kit uses Brembo calipers as does some of DoctorDiffs kit. He also sells a PBR based kit like Baer's. XV sells a PBR kit also.

Baer also makes some high end calipers themselves. The 4T, 6P and 6S kits are all custom Baer designs.

(I covered all of this in my B-body book. I did several chapters on brake systems in the book.)
