All of the current Chrysler "super cars" use what appears to be radial mount Brembo calipers but I don't have access to the tech info so I'm not sure. But just a casual look at the calipers on the SRT, Hellcat, Demon and Viper cars look like Brembo calipers to me. So there is probably some sort of corporate edict that says once the power to weight ratio gets greater than X then the car has to use Brembo calipers.
