Real world performance you can feel

We have fitted and run RP650 on our own builds and customer cars. Feedback has been consistently positive, with drivers praising the confident bite from the first press, stable performance when hot and the predictable pedal feel that makes braking easy to read on the road and on the odd track session. If you push your F8x hard, this compound keeps braking consistent when stock pads start to give up.
