Wilwood Front System for BMW M3 (1995–1999) and Z3 M Roadster 3.2L (1998–2001): 14.00-inch GT Slotted Rotors with Black FNSL6R

Black Superlite calipers and GT slotted rotors make this a 14-inch front upgrade for the listed BMW M3 and Z3 M Roadster applications. The six-piston package uses aluminum hats on the existing hubs and includes BP-10 pads. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among the disc brake systems and components Wilwood Engineering designs and manufactures. The Camarillo, California company was founded by Bill Wood in 1977 and supports motorsport, street-performance and specialized applications. Component selection must account for the requirements of the complete brake system.

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.
