Wilwood Red AERO6 Front Brakes with Drilled 14-Inch Rotors for Selected BMW 128i/135i/328i/335i/323i/325i/330i, Hats and Hoses Included

Red powder coating finishes the six-piston AERO6 calipers in this BMW front conversion. Drilled-and-slotted 14-inch rotors use the specified aluminum hats, and the supplied hydraulic lines replace the required flexible connection at each front caliper. Based in Camarillo, California, Wilwood Engineering was established by Bill Wood in 1977. It designs and manufactures disc brake systems, calipers, rotors, master cylinders, valves, fittings and brake lines. That range serves motorsport, street-performance and specialized applications; the individual parts must be matched to the requirements of the complete braking assembly.

Fitment & Compatibility

The application rows below contain important xi, rear-wheel-drive and body-style distinctions. Confirm the actual hub/brake arrangement as well as the BMW model designation. Provide the full wheel-clearance envelope required by DS1037, not simply an 18-inch rim label.

Use the fitment table below for the complete model, year, submodel and brake-option conditions; every listed condition must match the installed vehicle.
