Agree to disagree then /ubbthreads/images/graemlins/grin.gif I've read of more and more negative experiences with EBC Greenstuff pads on any number of vehicles. My wife had them on her auto Saab 9-3 a few years ago, and they would begin to fade after coming down on off-ramp. They're the worst popular pad on the market, in my opinion.
In addition to my great personal experience with the Porterfields, I've heard good things about the Hawk HP Plus. They're not really suited to for the track as some descriptions say, but are a good combo pad for street and autox, just like the R4S.
FWIW, I run the R4S in the winter in New England and they're great in the cold too. However if you don't really give a rat about you car's braking prowess and don't care to spend a little extra for good pads, just get some el-cheapo pads from Autozone.
