Here's mine after the last event.
My first event on these pads was done with stock tires/wheels and suspension. This time I was on KWs and 18x9.5s with 255 width 200tw tires. Additionally, the last track was pretty much all 2nd and 3rd gear, where as this track was 3rd and 4th, and one straight long enough for 5th. Long straights down to 2nd/3rd gear hairpins essentially. So much tougher on brakes.
The brakes did get pretty hot. I got ONE instance towards the end of the day where I noticed a slight bit of fade and the pedal getting slightly mushy, but I finished that lap as a cooldown lap and then carried on without issue; perfectly firm pedal again.
After some discussion with Mike, the wear pattern suggests that the fact I've been using the same rotors between street and track pads (switching before/after events) has caused some built up material. So I'm gonna get another set of rotors.
Aside from that though, I'm really happy with the pads. Easier to modulate than my old PMU CRs I've run, and a bit more braking force, and a lot more fade resistant. They worked pretty well on the stock tires, and they worked great on these 255s.
Expensive, yes; but if I'm able to get as many events as some of the other people in this thread, I'll be pretty happy.
