Product details

Black calipers and 12.88-inch SRP drilled & slotted rotors are the selected configuration. The 12.88-inch FNSL6R front conversion supplies six-piston calipers, rotor rings, separate hats and replacement aluminum hubs for No Limit Engineering ZG spindles. Bearings and mounting hardware belong to this specific fabricated-spindle package. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Each component must suit the surrounding brake system.

Fitment & Compatibility

Requires the matching No Limit Engineering ZG spindle. Substantial spindle machining is part of the conversion: remove the two interfering ears and drill/tap two mounting holes on both spindles exactly as DS-1543 describes, preferably through a qualified machine shop. This is not a direct bolt-on package for an unmodified spindle. Verify wheel pattern, register and caliper envelope. Hoses and spindles are not supplied.

For help selecting the correct brake package, give PMB Performance the vehicle details and measurements of the installed hardware. Our 20+ years of parts experience help resolve fitment beyond a model name alone.
