All new reproduction of Sumitomo's discontinued alumimum two (38.1mm) piston rear Z32 calipers. Finished in gold powdercoat and laser logos. Sold as a pair of left and right calipers with basic street pads and mounting hardware included. The ultimate setup will be to get 2 pairs of our calipers and a Z32 rotor from your local autoparts store & mount them on our dual caliper rear drop knuckles with our reservoir master equipped hand brake. Lots of information is available online about the other parts you may need to perform a complete brake system upgrade. *MAY BE USED ON BRZ WITH OUR KNUCKLE *Street pads grab quickly on cold rotors so that helps the hand powered brake response.
