This kit includes our “industry standard” single piece cooling plates for our large 12” road racing brakes. Utilizing 3” reinforced hoses, these brake duct cooling plates mount directly to the spindle, sealing the back of the rotor. This design forces air into the center of the rotor and out through the curved vanes, greatly increasing brake cooling while extending rotor and pad life. This all adds up to better braking efficiency and reduced rotor warping. The cooling plates are finished in a maintenance free, silver high-temperature thermal barrier coating.
