The unsurpassed braking capacity of the Forged Narrow Superlite 6R six-piston caliper serves as the base of this group of 13"-14" big rotor kits for these popular late model vehicles. FNSL6R kits are engineered application specific for simplified installation and full compatibility with OE master cylinder output and ABS functions where used. Big brake kits provide increased brake capacity and complimentary style with wheel, tire, and suspension upgrades on show cars and high performance street/track machines. Optional caliper finishes and rotor designs simplify personalizing the style and braking requirements of any application.


The Forged Narrow Superlite 6R (FNSL6R) is our newest version for the venerable Superlite caliper series adds the versatility and convenience of radial mounting to this widely popular caliper group. Radial mounting simplifies adaptation and provides two planes of adjustment for accurate alignment over the disc. These calipers integrate "Big Brake" style with Wilwood's latest technology to generate big stopping power in extreme environments over a broad range of vehicle applications.


SRP Drilled Performance Rotors feature a specially engineered directional cross drill and face slot pattern that improve brake response and pad performance throughout the entire range of light to heavy braking. The venting and cleaning action of the holes and slots will reduce pad glaze and disperse gasses and heat generated during the pad to rotor interface. The holes and slots also inhibit irregular pad compound build-up on the rotor faces resulting in smoother engagement and improved pedal response in all conditions. The material removed also contributes to lower rotating and unsprung suspension weight. Along with the excellent performance characteristics of this rotor design, each rotor is treated with a black electro coat to inhibit corrosion on all areas of the rotor. The high tech design, classic style, and aesthetic appeal of the SRP series are the perfect finishing touches to any wheel and tire detail.
