These premium grade cast iron hats are used with Wilwood’s internal shoe parking brake kits. Each hat is a precision machined, threaded hole design for use in conjunction with through-hole mount rotors. After machining, the hats are electro-coated for corrosion resistance.
The Superlite caliper series is the benchmark in short track, late model, modified and open wheel competition. It also enjoys prominence in a variety of road-race, off-road, rally and sport driving applications. The new FSLI model series is the latest innovation to this Superlite family of calipers. It has been redesigned with internal fluid ports that eliminate the external fluid cross-over tubes, along with any potential problems that could arise from a damaged tube. The transfer tube has been replaced with two additional bleed screw assemblies which allows this group of symmetrical piston bore models to be mounted either right or left in a leading or trailing position.
The new Aero4 forged four piston caliper delivers heavy duty stopping power for the road or track. The caliper incorporates race technology into a body design with widespread adaptability. Radial mounting, multiple options for piston volume, and a rotor diameter ranging from 12.88″ to 15.00″ give this caliper the versatility necessary to suit all types of heavy weight braking requirements. The new Aero4 is the latest innovation to the W4A / W6A series of calipers. It has been redesigned with internal fluid ports that eliminate the external fluid cross-over tubes and massive center bridge assembly.
The unsurpassed braking capacity of the Forged Narrow Superlite 6R six-piston caliper serves as the base of this group of 12.88″ rotor kits for these popular Import 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 /drift cars. Optional caliper finishes and rotor designs simplify personalizing the style and braking requirements of any application.
Steel rotors have applications in all types of motorsports. Steel rotors provide a durable lightweight option in applications where sustained temperatures remain in the low to moderate range, and high heat spikes are only observed on an intermittent basis. This could be anything from a hard stopping drag race car at the end of a quarter mile, or a high speed stock car coming in from a qualifier at a super speedway. Steel rotors can also be found in lighter weight open wheel cars such as sprints and modifieds, and a variety of light weight, open wheel road course racers. A special alloy and proprietary manufacturing processes give these rotors high resistance to thermal distortion with excellent friction and wear characteristics against the pads.
SLC56 front calipers are engineered as a high performance street and custom replacement for Corvettes and hot rods using Corvette suspension. These kits combine the high-tech styling and superior performance of the SLC56 calipers with the positive response, long wear, high fade resistance, and easy clean properties of the BP-10 compound Smart Pads. These kits are a direct bolt-on replacement for the OE calipers on all models of the C5 from 1997 to 2004, and all base model C6’s from 2005 to 2013 using the existing 12.8″ diameter OE dimension front rotors. The calipers attach directly to the Corvette spindle without the need for brackets or adapters and accept all types of OE banjo bolt style brake hoses.
Combination hydro-mechanical Parking Brake calipers use hydraulic pressure from the master cylinder for stopping power, and an internal mechanical lock within the caliper for a parking brake. CPB kits are built primarily for front wheel drive vehicles, and select rear wheel drive axles that are not well suited for internal shoe style parking brakes. The calipers are coupled with oversized two-piece rotor assemblies with aluminum hats and high friction BP-10 compound pads. CPB kits provide the correct balanced brake performance and matching style to compliment front big brake upgrade kits.
GT Series Big Brake Short Offset hats are precision machined from premium aluminum alloys for high strength and attention to minimized weight. Hats in this category feature threaded rotor mount holes for use with standard through-hole mount rotors. Threaded hole hats may also be used with T-Nuts or bobbins designed for use with specially machined slotted hole dynamic mount rotors. When used in conjunction with matched Wilwood rotor hardware kits, GT hats provide solid, reliable performance in the most demanding conditions. Short Offset Hats are for narrow space applications with offsets often less than 1.00″. They are available for most rotor bolt patterns in a variety of four and five lug wheel patterns.
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.
Wilwood’s Gen II Midget inboard hub & adapter kit provides a basis to provide dynamic rotor mounting of standard 6 x 5.50″ bolt pattern rotors. Hub & adapter kits contain: rotor adapter and dynamic rotor mounting bolt kit. Manufactured from high strength aluminum, it provides a lightweight and strong solution for rotor mounting. Gen II hubs offer improved clearance and easier install due to widening of the rotor adapter attachment bolt spacing. Also new high strength T-nuts and bolts round out this complete assembly.
