Wilwood Front Brake System, BMW M3 (1995–1999) and Z3 M Roadster 3.2L (1998–2001) - Drilled/Slotted Rotors in 14.00-inch Diameter, Red FNSL6R

Red six-piston calipers provide the visible finish change in this BMW front package. Its SRP rotors use 72 curved vanes within the 14-inch rings, mounted on aluminum hats around the original compatible hubs. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its component range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines. The requirements of the complete brake system govern the choice of individual components.

• Supply: one kit with brake components for both sides of the front axle
• Mounting hardware: included
• Hubs: not included
• Spindles, master cylinder and brake booster: not included

Fitment & Compatibility

Applicable models are the 1995–1999 BMW M3 and the 1998–2001 Z3 M Roadster with the listed 3.2L engine, as detailed in the table below. Do not extend this fitment to other E36 or Z3 brake configurations. The kit keeps the original front hubs and uses aluminum rotor hats; their listed clearance pattern is not a wheel-pattern conversion. DS-539 includes the installation and wheel envelope. Hydraulic hoses are separate, with 220-8799 specified for this application. Nominal minimum wheel diameter: 18 in; 457.2 mm. Compare the actual wheel barrel and spokes with the linked clearance drawing; diameter alone does not establish fit.
