ST47 Compound-
The ultimate competition brake pad? Maybe. If you want a brake pad with very strong overall friction, minimal wear and fade resistance for a competition brake pad the ST47 may be what you need.

With a temperature range rated at 1300?F the ST47 pad works well in high braking environments like the asphalt short tracks and the most severe road course circuits. ST47 pads are used widely in SCCA, NASA and other sportscar competition series. Mostly for dedicated track cars running slicks or very sticky tires.
