Hey Matt, yes they do have an E compound, but that is considered the high end of the street performance category.
Street Performance Pads:
Track Pads:
After reviewing these charts side by side I can understand why you wouldn't like the BP-20s on the track. They show a really shallow slope with the peak Cf (~.52) at nearly 900 degrees F! The E is slightly better, but still needs to be at 500 degrees F for max Cf (~.475).
I'm surprised that the track pads (A & H) have an initial Cf (~.55) rising above Cf (0.6) at 500 degrees. What is interesting is the initial cold torque is far superior to the street performance pads. I guess the major consideration is rotor wear
