The R4-S are no picinic at the track anyway, they fade readily and it's such a waste of a nice pad since you chew through them so quickly when they overheat. I'm done using "high performance street pads" on the track. Last time I only did it because I didn't know I was going til a couple days before hand. I'll actually probably put my stock pads back on after the Porterfields die and use the remaining 70% or so up. They'll be fine for autoX.
