Lots of bite. Way better than stock once they heat up; however, I don't have a comparison to anything other than the stock pads. The were highly recommended so it's what I went with.
I did cook my brake fluid with these pads at Summit Point main in the spring of last year which led to a quick fluid change at the track and the decision to install the SS brake lines and ATE Blue fluid. I haven't been back to the track since the upgrade of the lines and my new PSS tires. Needless to say I'm excited for the next event....waiting to see what end of Feb weather looks like for Summit Point Main.
