The Wilwood Narrow Superlite 6R big brake kit is a bolt on front upgrade built around forged Narrow Superlite 6R calipers and 14.00in 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.
