The Wilwood AERO4 rear big brake kit upgrades rear braking with W4AR calipers, BP-10 pads, and large 14.00-14.25 inch rotors matched to OE master cylinder output and ABS. Intended to complement front big brake systems, it retains the factory parking brake and improves stopping power, durability, and visual presence for vehicles with bigger wheels, tires, or higher braking demands.
