Brake pads?
 

For those of you running auto-x what pads do you run?
I'm gonna get stainless lines and new rotors, but I'm unsure of pads. I'm trying to decide between Porterfield R4s, Hawk HPS or EBC greenstuff.

Any feedback is appreciated.

Thanks,

Ben

BTW, I have a friend who called Porterfield, and they make the R4S for Q45 brakes! Might be useful for those who have swapped.
