Product details

The red AERO4/MC4 version supplies 14.00 by 0.81-inch drilled-and-slotted rear rotors. A dedicated MC4 parking caliper supplements each hydraulic service caliper on the matching Currie unit-bearing installation. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and builds disc brake systems for motorsport, street-performance and specialized uses, including calipers, rotors, master cylinders, valves, fittings and brake lines. Each part must match the requirements of the whole braking arrangement.

Fitment & Compatibility

The 14-inch rotor package is specific to the Currie Pro-Tour unit-bearing floating axle and its hub geometry. Follow DS-1181 for the AERO4 and MC4 caliper arrangement; front or rear vehicle names alone cannot identify this custom axle. Brake hoses and parking-cable hardware require separate selection. Use the 18-inch wheel guidance only with the clearance diagram for the actual wheel.
