Haven’t been able to get to the track as often as I’d like. Observations after a few more days at tracks - pad life seems pretty good. The rotor surface is smooth with these pads. When braking from higher speeds, (140mph or so) it seems that the initial bite isn’t as good or feels like I require more pedal travel then I expect to start to slow down. At slower speeds, the car slows down really quickly with little pedal effort/travel. Just seems it requires more effort then I expect at higher speeds. Not really a problem, just need to get used to it.
