The Wilwood AERO4-MC4 rear kit for 2015–2023 Mustang replaces factory rear brakes and retains parking brake function via the MC4 assembly. With AERO4R calipers, BP-10 compound pads and oversized 14.00" rotors tuned to OE master cylinder output and ABS, this kit offers stronger, more durable braking to complement front big brake upgrades and accommodate wheel, tire and suspension modifications.
