The Wilwood Forged Narrow Superlite 4R rear big brake kit pairs forged billet aluminum four-piston calipers with 12.88 inch vented rotors and BP-10 street performance pads. It retains full use of the OE parking brake, master cylinder output, and ABS where equipped, making it a complementary rear upgrade for 13 inch and larger front brake systems. Optional drilled rotor faces and caliper finishes let builders match style and performance.
