The Wilwood AERO4 rear axle kit upgrades rear braking with radial-mount AERO4 calipers, high-friction BP compound pads, and oversized 14.00" rotors while using the OE parking brake assembly to complement front big brake upgrades on late-model performance vehicles. Matched to OE master cylinder output and ABS function, the kit improves braking capacity, durability, and braking bias for vehicles with upgraded wheels, tires, or suspension components.
AERO4 Big Brake Rear Axle Kits replace the factory disc brakes and use the OE parking brake assembly as a compliment to front big brake upgrades on late model high performance vehicles. High capacity braking from the AERO4 radial mount calipers, High friction BP compound pads, and oversized 14.00" rotors are matched to the OE master cylinder output, ABS function, and individual vehicle bias requirements.
