4/2020 update - Calipers shipping out of USA and TW have laser logos paint matched instead of laser raw aluminum logos. All new reproduction of Sumitomo's discontinued alumimum four (40.45mm) piston front Z32 calipers for 30mm twin turbo spec rotors. Finished in gold powdercoat and laser logos. Sold as a pair of left and right calipers with race basic pads included. Pair these with a Twin Turbo Z32 rotor from your local autoparts store & match the rears which we sell separately. 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 and a 05-09 Legacy GT rotor (316x30mm $15 generic to $85ea for stoptech on rock auto).
