Porterfield R4-E track pads

[isrboss]

I will be using these pads in the front for the first time @ Sebring. Does anyone have experience with the Porterfields specifically the endurance compound? I hear the bedding is really quick on these. Is there any tips/help for a guy using track pads for the first time with Bridgestone RE-11's?
Thanks

I used regular R4 race pads (not the 'E' compound) on my old '96 Porsche 993. Liked them a lot. They were one of the favored track pads, besides Pagid 'Orange', among a lot of Porsche guys. Been thinking of trying them out on my Boss.

I also used the R4 in the past. They did not have much initial bite (compared to Hawks at least), but good stopping power. And they were quiet on the street when I was too lazy to swap.
