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). *These pads need to go through several cycles of being very hot to bed into the rotor. They are totally functional out of the box but require extra stroke for lockup until they are seated on the rotor surface. ~ Extra caliper paint is available as a $30 option in cart in case you just buy our fronts and need to paint your rears. ~ Liquid paint is shipped with reducer, shake well before using. Spraycan propellent is included. Dissassemble rubber piston seals & boots. Prepare the surface so its clean, dry, degreased (maybe sand blast for best results). Wait 30 minutes for the paint to dry before baking in the oven at 140c 284f for 50 minutes. Allow plenty of time for the paint to to cool and completely harden before rebuilding and reinstalling.
