Lightweight Package, Heavy Duty Performance!
Wilwood's Superlite billet SL6 series brake caliper integrates ''Big Brake'' style and technology into the traditional 3.50'' centered lug mount caliper category. Each Superlite SL6 caliper is precision CNC machined from high strength billet into three specialized configurations that cover a broad range of competition and sports driving applications. Wilwood's superior performance of the SL6 comes from the extremely durable, efficient and lightweight body design. Starting at 5.06, pounds it is the product of computer generated solid modeling and FEA stress analysis technology. Full length stiffening ribs and a reinforced radial transition from the piston bore housings to the closed end bridges have produced the strongest Superlite caliper bodies ever built. When compared to open bridge calipers that use tube or stand spacers between the body halves, the closed end bridge design is measurably stronger with less separation or deflection under load. Additional strength and resistance to deflection comes from the four high-strength steel end bridge bolts. A fifth center bridge bolt provides even more overall strength and easy access to the pads without the need to remove the caliper from the mount.
A unique six-piston differential bore configuration provides balanced loading for even pad wear in sustained high heat environments. The standard SL6 calipers feature one-piece stainless steel pistons. Stainless is used for its slow heat transfer properties and high resistance to corrosion. The SL6/ST models feature Wilwood's exclusive Thermlock pistons. This multi-part piston design creates a highly efficient thermal barrier to further reduce heat transfer from the pads to the caliper body, seals, and fluid. Cooler temperatures translate to longer service life and less chance for heat induced pedal fade.

In addition, each SL6 is equipped with SRS bridge plates. SRS plates eliminate all bridge wear caused by 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 harmonic vibrations that contribute to pad squeal. Two piece bleed screws and dampened fluid tubes are recess mounted to shield them from track debris and other potential damage sources. High temperature, square faced bore seals provide the largest possible sealing area and controlled piston retraction on release. The full range of Wilwood pad compounds is available to match the brake response and heat range of any competition or sports driving application.
Calipers in this group feature a full width reinforced rib outboard body for maximum strength when caliper to hub or caliper to wheel clearance is not an issue. These calipers are primarily used for asphalt stock cars, road racing, and other competition applications with small 5 on 5 or other OE type lug patterns. The caliper bridge radius will clear rotors from 11.75'' to 13.00'' in overall diameter. These calipers in this group come in a couple of pad options, either use of 7420 type 20mm thick pads or the 7416 type 16mm thick pads.
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
