The Wilwood Aero4-MC4 Rear Disc Brake Kit (140-13888-DR) is designed to be a performance upgrade for 2015-2020 V6, EcoBoost and GT Mustangs. This Wilwood Rear Disc Brake Kit will replace your factory rear disc brakes and uses 4-piston rear calipers and a separate MC4 parking brake assembly. This kit includes a pair of 4-piston calipers that feature stainless steel pistons and are finished in a durable red powder coat. The rotors in this kit are drilled and slotted and have a vane count of 36 per rotor, helping to reduce the heat produced when heavy braking is needed. The rear rotors are a two-piece design that features an aluminum rotor hat that is finished in a black e-coat. Wilwood includes a set of BP-10 brake pads that have a compound SmartPads. This allows the kit to provide high response and holding power when cold and resistance to fade when hot. The Rear Wilwood Disc Brake Kit (140-13888-DR ) is a complete bolt-on installation, meaning no modification is required. This Wilwood Aero4-MC4 Rear Disc Brake Kit is proudly made in the USA!
