Planet 9

I use my CS only for track or mountain twisty road driving, on a rare ocassion I take it to drive in the city.
What brake pads would you guys recommend?

Well I'll jump in here before Craig@Rennstore.com (sponsor) does, and suggest Pagid Yellows. Great on the track, easy on the rotors, but they do squeal a bit in normal driving (though you might be able to minimize this by beveling the leading edges as Craig described in another thread - Link: http://www.planet-9.com/cayman-box...-solution.html)

When you say great on the track, means more stopping power or less brake fade or both?

I have Pagid yellow, and they have better stopping power once they warm up, and less resistance to fade than the original pads. Mary that with ss braided lines and Motul 600, and you have a nice track setup. They squeel like a pig when cold and have a smal reduction in performance.

I have a set of street pads I change when I am not at the track. I am happy with the combination for the way I use the car. I also use the car for the street.

Pagids are very popular for Porsches, but some here also use Performance Friction (PFC) 97 compound. For spirited road driving and autocross I still prefer OEM pads to track pads. Track pads need some heat before they reach optimum slowing rate, and they may squeal some under light applications such as normal driving and slowing. Pads are easy enough to switch at the same time one mounts track wheels/tires for track events.

I hesitate to answer for KS-CS, but I suspect he means that track pads generate a higher slowing rate because they produce more friction or torque against the discs. That does generate more heat, but track pads are designed to handle the extra heat. The extra heat does transfer to the discs and brake fluid, however, so high boiling point brake fluid helps to manage the heat and prevent brake fade. I still don't know how to prevent discs from getting heat cracks, however.
