Having had a set of Porterfield R compound pads in my old 4k turbo with good
results, I installed a set of Porterfield R-4S's about a week before the NW
QCUSA track event at PIR back in November, My experience with them was not
the best. They did work well on the street, good stopping power, some but
not a ton of dust and a little noise.

On the track they appeared to be working well until about 15 minutes into
the session when they just went south on me. Loss of Pedal, loss of stopping
When I came back in and cooled the brakes down I found that my pads were 90%
gone and the UFO's were destroyed.

The thing that bothered me the most is that I was not using them as hard as
I had used the stock pads at Bremerton about 3 months earlier with no I'll
