Wilwood 4-Piston Sport Rear Brake Kit for 2006-2015 MX5
(12.88" Rotor)


Wilwood 4-Piston Rear Caliper Kit - Red
Dynapro 4 Radial-MC4 Rear Axle Kits replace the factory disc brakes and use the MC4 parking brake assembly as a compliment to front big brake upgrades on the 2006-2015 MX5 Miata. High capacity braking from the Dynapro Radial calipers, BP-10 compound pads, and oversized 12.88" rotors are matched to the OE master cylinder output, ABS function, and individual vehicle bias requirements. Enhanced brake performance, increased durability, and high-tech style compliment big wheel, tire, and suspension upgrades on customized MX5s with increased brake requirements. Optional caliper finishes and slotted design is ideal for both street and track applications.
