Forged Narrow Superlite 4R Front Brake Kit

Motorsports-proven Forged Narrow Superlite Radial mount caliper, with oversize rotor are engineered to bring 1969-89 Porsche 911s performance braking capability on par with the 1974 RS and 930 turbo, using lightweight components and modern USA manufacturing techniques. These kits combine the latest Superlite four piston caliper, used in countless laps of many competition classes, with 12.19” (310mm) diameter GT slotted or SRP series drilled and slotted e-coat rotors, and the positive response, high fade resistance, and easy clean properties of the BP-10 compound Smart Pads. Forged aluminum calipers, mounting hats, and bracket outperform stock parts while weighing less. These kits bolt directly to front struts with 3.00” (76.2mm) spaced mounting tabs without modification. Braided stainless Flexlines are included.
