Too bad because I really enjoyed them as a street pad, but definitely not something you can be aggressive with in high speed twisty roads.
Ultimately I lost confidence in my braking about half way into the run and the pad lost a small chunk of pad material during the process. It seems like when these pads exceed their temperature rating, they become very inconsistent. High initial bite followed by very mediocre braking behavior.
I am going to have to step up to a race pad and deal with dirty wheels every other day, but I will learn to live with it to avoid having a miscalculation at higher sustained speeds  |
Porterfield says that this compound is not for track day use (sounds like you're pushing HARD).
For the tooling around town, these sound okay, but not for what you're doing.
Suggest you consider RacingBrake or endless for pads that will be up to the task.
