Thanks mist, on my last GTSt I used SS-S, they were very nice on the street, but cracked the poos on the track. The R33 GTSt is just too heavy for them, with that swept area disc. I think I will order some CC-X's, but I believe they are very heavy on rotors.
I've also got a set of Hawk pads in the garage (came with the car) any good?
