i had redstuff on a focus i used to have, and they ate my disks so quick, the only plus side is that they are basicly zero dust :), oh and also when they get realy hot they are fantastic, i thought average when cold ie braking on a moterway, i have no experiance with yellow stuff, and dont think i would use redstuff again unless i was doing a track car, and then im sure there are better options :)
hope this helps
