This compound is specifically aimed at advanced track day users and offers full race performance under track conditions. While it can be used to drive to and from the track, some brake squeal will be experienced during street driving. It is not recommended that this pad material be used for extended daily street use as accelerated disc wear and brake noise will be experienced during daily street driving. On track this compound will offer unmatched brake performance and fade resistance and will be a significant step up over APR's Advanced Street / Entry-level Track Day compound. The material remains kind to discs under track conditions and pad wear is low. It has a slightly rising torque curve and modulation remains excellent. A mechanical retention system is employed between the pad backing plate and the friction material for maximum shear resistance during high-temperature use. Advanced track day users will really appreciate the characteristics, performance and wear life that this compound offers. For advanced track day customers that also use their car as a daily driver we suggest a two-pad strategy in which you run APR's High-Performance Street compound for daily street use and then switch to APR's Advanced Track Day material for track events.
