My experience is with Hawk and PFC.

PFC 80: good on the track, semi-kind to rotors, mild brake dust, need some heating up to be useful.

PFC 97: about the same as the 80 on the track, a little less brake dust, need less heating up to be useful. A good dual purpose PFC pad. I liked them.

Hawk Blue: A little better on the track, lots of brake dust (more like metal shavings), eat up rotors, noisier, need a lot more heating up. Good on the track, not so much for street/track dual purpose.

I just got a 930 setup for my Carrera and went with Pagid Orange for a dual purpose pad, as recommended by Steve at Rennsport Systems. Never used them before (and won't get to try them until the runway I land on is more than 400 feet long), but they come highly recommended.

Good Luck.
