This caliper is CNC-machined from aerospace-grade billet aluminum. Surfaces are hard-anodized to achieve close working tolerances for unsurpassed performance and accuracy. The billet caliper support relocates the caliper below the axle to lower the center of mass and allow for easy wheel removal. The kit, which is compatible with the stock disc, replaces the stock caliper and comes complete with sintered pads for street or racing use. Includes thermotape caliper stickers and complete installation instructions.
