A Simple, Bolt-On Brake Upgrade!
ProMatrix Brake Pad and Rotor Upgrade Kits offer measurable brake performance improvements to racers and enthusiasts using the OE factory brake calipers. High-performance pad compounds are specially selected to provide increased brake response and higher resistance against fade. A choice of either two-piece directional vane GT Curved Vane rotors that provide high-temperature durability for the track or SRP Drilled and Slotted black e-coat rotors that provide high-tech style with corrosion resistance for the street. Wilwood Promatrix pads feature specially selected compounds for enhanced performance through increased friction properties and extended temperature range. ProMatrix compound pads are proving to be the most versatile dual-sport compound with medium friction, moderate temperature range, smooth but aggressive initial response, and low wear rate. These pads offer clean and comfortable responsive driving on the street with enough friction and fade resistance for high-level autocross and high-performance driving.

GT Curved Vane Rotors are built for the extreme conditions of professional motorsports. The superior heat absorption and dissipation characteristics of these heavy wall directional vane rotors are the keys to preventing heat fade and realizing long service life from rotors and pads. All rotors are cast from premium grade, long grain carbon iron for long wear, thermal stability, and distortion resistance. Every GT Rotor is detail machined to eliminate stress points and unnecessary weight away from the pad sweep face. The faces and OD are precision turned to less than .001'' for flatness, parallelism, and run-out. An asymmetrical face slot pattern provides smoother engagement through reduced harmonics and improved thermal balance between the ID and OD of the rotor. Every rotor is then individually dynamic balanced to provide vibration-free performance at any speed. These rotors provide the highest cooling capacity and longest service life for extreme braking on short tracks and road course competition.
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 gases 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. Along with the excellent performance characteristics of this rotor design, each rotor is coated black. The high-tech design, classic style, and aesthetic appeal of the SRP Series are perfect finishing touches to any wheel and tire detail.
NOTE: These Brake Rotor Upgrade Kits DO NOT include brake lines. Wilwood's website and installation instructions have NOT been updated to reflect the changes that Wilwood has made to NOT include brake lines in these kits any further.
