Wilwood Front FNSL6R Brake Kit for BMW M3 (1995–1999) and Z3 M Roadster 3.2L (1998–2001) - 14.00-inch GT Slotted Rotors, Red

GT slotted rotors and red FNSL6R calipers distinguish this front kit for the listed BMW M3 and Z3 M Roadster. It replaces the service-brake components while retaining the hub and spindle, with hydraulic hoses selected separately. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Founded in 1977 by Bill Wood, its range covers calipers, brake rotors, master cylinders, valves, fittings and brake lines. Individual parts must match the complete brake system and its operating requirements.

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.
