The Wilwood Narrow Superlite 4R big brake kit is a bolt on front upgrade built around forged Narrow Superlite 4R calipers and 12.88in rotors. The SRP rotors are drilled and slotted to vent gas and dust and shed heat under repeated hard stops. Calipers wear a black powder coat. It ships as a complete kit with calipers, rotors, mounting brackets, brake pads and hardware.
