This Street Performance Drilled and Slotted Brake Kit provides increased levels of strong braking. The complete package includes drilled and slotted rotors, premium brake pads and calipers representing the latest racing technology. The calipers are available in various finishes to reflect your individual style. Originally used for serious competitions because of their advanced cooling capacity, drilled and slotted rotors now became popular in street applications for their pure aesthetic value. Whether you have a daily driver or something ready for the show, this Street Performance Drilled and Slotted Brake Kit is what you need to get optimized braking performance.
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. This rotor design by Wilwood combines the best features of a slotted rotor and cross-drilled rotor allowing your brakes to run cooler and sweep away water and dust. The cross-drilled and slotted rotors improve air circulation and increase brake pad bite, ensuring incredible stopping performance.
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.
