The Dynapro 4 Radial-MC4 rear axle kit from Wilwood replaces factory disc brakes and integrates the MC4 parking brake assembly to complement front big brake upgrades on late-model high-performance vehicles. It pairs Dynapro Radial calipers, BP-10 compound pads, and oversized 12.19" rotors, matched to OE master cylinder output and ABS function for correct vehicle bias. The kit improves braking capacity and durability while supporting big-wheel and suspension upgrades.
