SL6 Calipers

SL6 calipers are pure performance featuring a fully CNC machined billet body with closed end bridges and a reinforced bridge to body transition. Center bridge body bolts provide additional strength and positive retention of the pads. These elements combine as an ultra-rigid body that resists separation and deflection under high load. Driver comfort and confidence soar with immediate response from a very firm pedal. The SL6 generates high clamping force and balanced pad loading from a race-proven differential bore six-piston configuration. Staggered piston sizes distribute pressure to compensate for the natural variances in temperature, load, and wear rate that occur over the length of the pad. Pad life is extended and performance is measurably improved. Stainless steel pistons are used in all custom show and sport performance applications for their low heat transfer properties and resistance to corrosion. Road race kits feature SL6/ST calipers with Thermlock pistons for maximum heat protection in extreme heat environments. High temperature, square faced piston seals provide long service life in extreme environments with positive piston retraction on release. Stainless steel SRS bridge wear plates eliminate pad gouging and extend the service life of the caliper. The spring-loaded action of the SRS plates also eliminates pad rattle and dampens the vibration harmonics that contribute to pad squeal. Fluid tubes are dampened to eliminate vibration stress and recess mounted for protection from track debris. SL6 calipers bear Wilwood's signature and a high luster black anodized finish in a style that will catch the eye and win the favor of the most discriminating enthusiast.  Calipers Available in Black or Red.

14" Rotors
Large diameter vented iron rotors provide substantial increases in cooling and stopping power over small diameter OE rotors. All Wilwood rotors are manufactured from premium grade, long grain carbon iron to provide long wear with high thermal stability and resistance to distortion. The superior heat absorption and dissipation qualities of a directional vane iron rotor are essential to preventing heat fade and realizing the longest service life from the pads and rotors. For custom, show, and high performance sport driving, SRP rotor kits offer the high-tech look and improved performance of a directional cross-drill and face slot pattern. In addition to their aesthetic appeal, the venting and cleaning action of the holes and slots will reduce pad glaze, dissipate surface heat, and minimize irregular pad build-up on the rotor faces. The results are smoother engagement with improved consistency and response at the pedal. Every SRP rotor is treated with a black E-coating to reduce corrosion on the areas of the rotor not kept clean by pad contact. GT rotor kits feature Wilwood's ultimate competition rotor with full detail machining, asymmetrical face slotting and individual dynamic balancing. GT rotors run true and vibration free with extended rotor life and pad wear on applications subject to higher sustained operating temperatures.

PolyMatrix Brake Pads
PolyMatrix brake pads get fast response with high resistance to fade, long wear, and the low rotor abrasion that PolyMatrix is so well known for. Specific pad types and compounds have been selected for each application and are listed in the service parts guide for each kit.

Caliper Brackets and Hardware
Aluminum mount brackets are lightweight and strong. Each bracket is CNC machined for precise fit on each specific spindle. Grade 8 strength or higher nuts, bolts, studs, washers, and alignment shims are included with each kit.

Plumbing

Fittings and flexlines to install these brake systems are included. 

*This Brake Kit may require 19-inch or larger wheels and/or wheel spacers. Please refer to the wheel clearance diagram to check to see if it will fit your specific wheel.

Notes

Black Calipers. See separate listing for the red caliper system. Installation of Wilwood Disc Brake Kits may affect the wheel offset and may require a larger diameter wheel and/or wheel spacers for caliper clearance. All returned orders are subject to a re-stocking fee, so please make sure your wheels will work before ordering. Shipping Promotions are valid in the Lower 48 States only.  For all other areas, please contact us for a discounted rate quote.
