Aggressive pads
 

I want to upgrade to a more aggressive pad on my 912. My current setup right now is stock calipers front and rear, 19mm master, braided lines, Ate blue and Repco Metal Master pads front and rear. Right now I'm leaning towards the Porterfield R4S pads. But on a college students budget, I'll have to do the fronts first, and the rears next month.

Any suggestions? The car is a daily driver, with hopefully an occasional autocross or track day thrown in.

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.
