lots of brake dust with these?

 

The brake dust in not bad with PFC. Lot less than OEM. 06 compound is no longer made, hence the 08/11 recommendation. If you are not running on a racetrack, I would not run these. They are race pads designed to work optimally at much higher temperatures and take a lap or so to heat up. You will never heat them up properly on the street and they will eat rotors like crazy when cold. They have decent bite when cold but need to be hot to work optimally.. If you track frequently you can run these on the street between events but if you don't track then there is no point to these on the street. I would run Endless MX72 as a street pad that still works very well on track.

 

I'm running the 08/11 combo(OE GT2 brakes, steel rotor conv.), great bite, but think I could use even more rear bias...will see how they are next season on better tires at track.
Very loud once warm but tons of stopping force. Got mine from Clark@ ApexPerformance...awesome guy to deal with!
Agree with pwdrhound about street use, not optimal for street only

 

I switched to PFC 08 summer '13 and have about 8-10 track days and 5000 miles on them. Looks like >50% pad left; brake dust is minimal compared to oem; and squeal is minimal or non existent if the pads are brought up to track temps once in awhile. They do seem to be tougher on rotors but I would have been due for a new set of those in the spring in any event. Highly recommended!

 

Rob,
Install the larger rear 997GT2/3 PCCB calipers. I think you already have the larger MC. This will balance it out. I have the 997 brakes and just switched to 11s from 08s this weekend and like it even more. It seem like you can't get enough rear bias on these cars..

 

have been thinking this is inevitable for a while now...planning on number crunching a bit to see if stock front setup would work with a 997 rear caliper upgrade...or has this been a confirmed combo? 997.1GT3 'steel' brake front piston sizes vs. 996GT's?
would like to keep the 350mm front discs, at least for the time being, for easy wheel selection.
Might be a nice upgrade once I burn up the current pads, or sooner...
Cheers,

 

Yes, it's a confirmed combo. Your yellow 6GT2 front PCCB calipers are the exact same calipers with the same piston sizes as the red 997GT3 front calipers on the 7GT3s with 350/350 steel brakes. As a matter of fact all the front 6GT2/3 6 piston calipers are the same as the front 7TT/GT2/3 calipers that use the 350 rotors.

 

Thanks mate! ...will be looking into some rear calipers next season.
IIRC, it's the 380mm version 997's where the piston size are different GT vs TT, correct?
Cheers,
Rob

 

Correct. The 380GT front calipers have smaller pistons than the TT versions thus shifting the bias further rear. This helps rotate the cars under hard trail braking.

 

Bingo, rotation and general threshold bias is by far the biggest issue I have with the car
Would be nice to rely less on the rear sway to rotate the car and use a bit more trail brake and allow harder out of corner accel.

 

Where are you on your sways? I'm one hole from full stiff in the front and one from full soft in the rear on basically same front to rear spring split (1400/1500).
Car rotates beautifully under hard trail braking without any tendency to swap ends. It's very progressive. This is on NT01 245/305s

 

1 from full stiff front(2 of 5), 1 from full stiff rear(2 of 4)...I haven't touched anything suspension related yet...this winter will be all monoball/heim-joints and probably rebuilt/revalved OE Bilstein dampers...corner balance and alignment
Will be doing BFG Rival's 245/315

 

Great info here guys. As somewhat of a noob to road racing, anything you guys recommend on the stock 2003 PCCB setup, other than replacing them with a steel rotor setup etc? Are the stock PCCB pads good and strong enough for aggressive driving as long as they are replaced accordingly?

Car has pss9 and R888s on Fikses. Just did an event and in the rain out of all times. I was nervous because of reading R888s being terrible in the rain. Needles to say, I learned a TON in the rain and was very surprised on how well the whole car performed all day. Several spin outs by other cars and mine got tail happy twice but controllable. Glad my other track junkies pushed me to continue with the event even in the rain.

 

I have used Endless MX72 (blue) and Race Technologies RE10. Both were big improvements over stock.
