track pads and brake fluid

[freeform911]

what's up guys...I've read through a number of post but haven't found much...the car is a mostly stock 86 911 with boxster front calipers...stock rear...both the wife and i de the car between 10-15 events a year...she's white solo...i'm black advanced solo..the car is usually ran back to back, meaning one of us get off the track and the other goes back out...since we started about 3 years ago I've ran pagid black all around...so my question is, is there a better pad to run?..maybe something with a little more bite...that's still semi rotor friendly...i also run ate 200 fluid...is there something better...and just an fyi we don't have an issues as of now with this set up just seeing if there's something else better....sorry for being so long winded for such a basic question...
thanks in advance for any recommendations....steve

You could try PFC 11 pads. Good bite and friendly to rotors. These are the pads I use on my race car.

Ate Type 200 is okay brake fluid. If you are boiling it, try Castrol SRF or Endless RF650.

Thanks winders...pfc 11 all around?

[winders]

Yes. I buy them from Clark Hamerly at Apex Performance:

Raybestos ST43 is my fave. I used to run pagid Orange, Until I had to replace rotors at the end of every season, and pads at least twice a season. The ST43's stop just as well, with maybe a little less feel... But I can go 2 or more seasons on rotors, and the pads easily last 2 to 2.5 times longer, at HALF the price!!!
Motul 600 is what all the racers out west prefer...

Pagid RS14 black has a lot of bite and is hard on rotors, PFC or the newer Pagid RSt3 or RSL1, You may not need as much bite as you think in which case Pagid 29 is much easier on rotors.

there are lots brake fluids that work well at higher temps here are some in order ranked by wet boiling point
Mfr Type DOT WetBoil DryBoil Mix
Castrol React SRF DoT4 518 608 yes
Torque RT700 4 439 683 Yes
Project Mu G-Four 335 4 430 635 NO

AP Racing Radi-Cal R3 4 399 617 Yes
Brembo LCF 600+ 4 399 601 Yes
Pagid RBF 4 399 626 Yes
ATE Super Blue 4 396 536 Yes

Castrol SRF has a lot to recommend it if this is a street driven car because it has (last time I looked) the highest wet boiling point, along with a very trackable dry boiling point.

Though what may be more important is the fact that you are not boiling what you are using despite the back to back driving. I'd not be in a hurry to change fluid (other than routine replacement) until you start noticing a slightly mushy pedal.

Just an update..I decided to run pagid rst3 front and stayed with blacks for the rears...I also stayed with ate 200 fluid...but will be changing that as I think we might be boiling it...the rst3 are alittle more aggressive then the blacks...it took a few laps around the track to get the feel but at the end of the day pretty happy with how they feel...thanks again Steve

I was not happy with 6-month old ATE Super Blue in my car. Boiled the brakes pretty thoroughly, just about every run group.

You haven't mentioned brake cooling. With back to back runs, you want direct cooling to rotors and calipers. The other variable is duration on the pedal. More duration is more friction is more heat.

No direct cooling, unfortunately...I know I should do something for brakes as far as cooling just haven't gotten around to it...as far as duration, we are both pretty aggressive on the brakes, so we don't sit on them to long...

Pagid oranges, motul 600. I used to use blue but thats all gone and old school.
The biggest difference i saw in on track performance was cooling. And it was advice given to me from another pelican when i asked the same question as you. Get air into those rotors and the reduction in temp will let everything else work better. your car has more than enough braking potential than you need, just have to keep it within its optimal operating range.
