I haven't swapped mine yet, but when I do, I'm going to try the EBC brake pads, probably Redstuff. I have 2 friends who are using Hawks and they seem to be quite happy w/ them.
I use Ceramic Pads, but when i first used them i didint realise that they'd eat up my Stock rotors! DOH!
But now that my rotors are replaced i use Ceramic pads. Very nice against high speed stopping that creates heat.
