A Street Performance GT Slotted Brake Kit by Wilwood is engineered for your specific vehicle and will give you premium brake control you need on the street, track, or during your everyday driving. The kit features GT Slotted rotors, multi-piston calipers, and premium brake pads altogether providing exceptional braking performance and a long service life. Slotted rotors feature an asymmetrical slot pattern for smoother pad engagement. Developed to withstand extreme temperatures, GT rotors possess the highest possible degree of resistance against distortion, warping, cracking, and wear. Regardless of the driving environment, the Street Performance GT Slotted Brake Kit makes stopping as exciting as accelerating.
Fixed calipers by Wilwood offer unmatched stopping power. The pistons in fixed calipers are located on both sides of the disc, allowing for evenly distributed clamping force. They apply more squeezing power and apply it more evenly during braking as force is directly applied to both sides. Multi-piston calipers allow for more even braking and, as a result, less pad distortion. The more number of pistons a caliper has, the more clamping force it provides. Thanks to the evenly distributed pressure, these calipers ensure an even wear pattern along the entire length of the brake pad. Usually these calipers have smaller diameter pistons than single-piston calipers.
The internal vane design of these vented rotors by Wilwood provides excellent heat dissipation during brake cycles. As the wheel spins, the vanes around the edge of the rotor draw air in and pull it through to help cool the rotor. With the extra heat dissipated there will be less brake fade. Slotted rotors by Wilwood are a great alternative to drilled rotors. They serve the same purpose of breaking down hot brake gas but provide better resistance to cracking. The slotted pattern allows for increased pad bite and improved air circulation. The slots help to sweep away water and dust. If you drive hard, race or use your vehicle off-road or for towing purposes, slotted rotors are a perfect choice for you.
Wilwood® Engineering designs and manufactures high-performance disc brake systems. Since founding in 1977, Wilwood has developed a substantial matrix of brake components and engineering techniques that allow us to quickly and reliably create brake systems for almost any application. Their core ability is the rapid development of custom engineered brake systems using a combination of off-the-shelf and custom components. In addition to designing and manufacturing brakes for all types of competitive motor sports, Wilwood also manufactures brake systems and components for agricultural equipment, industrial applications, utility vehicles, snowmobiles, quads, motorcycles and military vehicles.
