I have for sale a front and rear set of Brembo 4 Piston Calipers. These came off of a Model S due to being aftermarket painted. They are in perfect working condition. These are the same as what came on mid 2000's CTS V's and use a 15" rotor. The calipers need a good cleaning from road grime, and probably a repaint for most people's taste. Pads have good life, aroud 7mm . Asking $450
