The Wilwood AERO4 rear axle kit upgrades rear braking with W4AR calipers, BP‑10 compound pads, and oversized 14.00 inch rotors to replace factory rear discs and complement front big brake systems. Matched to OE master cylinder output, ABS function, and vehicle bias requirements, the kit enhances durability and provides high‑tech styling for late‑model Corvettes — specified for 1997–2004 Corvette C5/C5 Z06 and 2005–2013 C6 applications.
AERO4 Big Brake Rear Axle Kits replace the factory disc brakes and use the OE parking brake assembly as a compliment to front big brake upgrades on late model high performance vehicles. High capacity braking from the W4AR calipers, BP-10 compound pads, and oversized 14.00" 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 vehicles and all others with increased brake requirements.
