News From circle track Land. still a little bit off from Sebring 12 hour news.
Congratulations to Kurt Busch . Winning the Daytona 500 with PFC 01 compound.
also congratulations to Brad Keselowski on his Atlanta win. PFC 01 compound.
OG racing had an Invite to the Testing of the new Panoz GTS car. Equipped with a full PFC package. Compound undetermined yet. will release that information after first race. Blurred for security.
Below photo released by Panoz.
PFC Is the fastest, Proof is on the podium.

-PFC Full carbon carbon brakes on for IndyCar testing. Drivers did back to back blind testing and picked the cars equipped with PFC brakes . As a result, PFC will be spec brakes of choice for the 2017 season.
In a blind test conducted at multiple tracks, PFC's discs and pads earned rave reviews, and after years of complaints regarding uneven brake temperatures, high wear rates, and excessive vibrations, braking could become a happier topic to broach with drivers next year. -Racer Mag link here
Torq is the working force of the pad. all pads have heat ranges. the pfc 97 has a huge heat range as it goes from 100*-1400* it's Torq output is low near .37mu. making it good for smaller tires and rough tarmac. but over it's heat range the torq output will only change 6% through 100*-1400*. for reference, a hawk dtc70 changes 20% from 700*-1200*.
The fastest Combination of PFC pads is to run them square. We have found that with PFC's low bite and consistent Friction that we can run a higher Tq rear pad and keep the car stable. this gets a PFC equipped car faster deceleration rates than a car running a staggered pad option
Any feedback from the SM crowd as to why many have stuck with the PFC-97 even with the change in tires from Toyo RA1/ 888 to something more aggresive (Hoosier)? Looking at the recommendation breakdown it would seem the PFC-11 should be the most applicaple pad to the current SM ruleset?
Is it strictly pedal feel, or was that pad really having issues on standard blank rotors, etc.?

when the 97's disappeared in 2015 SM guys tried everything. Carbo, project Mu, and even Padgid. Nothing was as fast as the 97's. the racers didn't like the 14, the torq output was too low and fluid boiled when used with slicks. The 11's were too aggressive for the SM mandated non-slotted rotors. the rotors coming from mazda was some of the worst iron ever seen. Racers loved the Torque and consistency of the 11 but a rotor would start to deteriorate. They would deposit iron in the pads, causing loss of performance. a slotted rotor would easily correct this issue but was not allowed under SM rules. The demand for the 97 became too big for PFC to ignore early 2016 and the 97 went back into production.

RAcer magazine Covers PFC's Fix for Indy car. 2017 Indycar removed Brembo and replaced all cars with PFC brake systems.
BRAKE BALANCE
The big question after the race centered on the relative lack of brake temperature-related drama, and IndyCar's competition department deserves credit for turning a major concern into a manageable situation. Thanks to a second round of brake duct modifications granted by the series on Saturday, Honda teams were able to add new extensions to the lower rear brake ducts that were quite effective.
According to one engineer, the first round of cooling modifications from Thursday for the front and rear ducts, combined the Saturday update for the rears, helped reduce temperatures by approximately 75 degrees F, which "got us out of a panic and into [an] acceptable [situation]."
Elsewhere in the paddock, other engineers shared the same praise for IndyCar, but left St. Pete with concerns about future road and street course races. As many drivers were lifting early entering the braking zones to save fuel in the race, a faster pace and more aggressive braking could create problems that weren't triggered on Sunday.
"We had some headroom, but wouldn't ever target running and hotter; that was about the top of the comfortable window," said one engineer, and another described brake temperatures while running in traffic as "borderline."
IndyCar and its manufacturers don't have much time to come up with a third round of cooling options before the series heads west to Long Beach but if the collaborative effort at St. Pete can be used as a reference, smart fixes will continue to be approved when they are needed.
As one of the engineers remarked after Sunday's race, "I will say we made more improvements to the brakes in the last three days [at St. Pete] than in five previous years."
Every time I see the notification for this thread I keep reminding myself to get a set of PFC97 to play with at autocross. On the other hand, where do I get a sweet jacket like that?!
PFC 7754.xx.16. 44 pads for the new Stoptech calipers. available in 01 and 97 compounds.
01 compound. the high Torque option. The daddy of professional motorsports with hundreds of professional championships.
The 01 compound offers a mild bite, to help your tires keep prevent flat spots.
Consistent Tq output from 200*-1600* to keep your pedal feel the same lap after lap, turn after turn.
Fantastic modulation for easier trail braking and faster lap times. Recommendations:
Miatas with 200-20 Qutg tires, and little to now downforce.
suggested balance is to run compound Square 01 front and 01 rear. click here for more information.
97 compound Low torque option. excellent pad for beginners with low to no downforce, and harder tires.
The 97 compound offers a mild bite to help prevent flat spots.
Consistent torq output from 70*-1400* to keep your pedal feel the same lap after lap, turn after turn.
Fantastic modulation for easier trail braking and faster lap times Recommendations:
Miatas with 200-500Qutg tires, and little to now downforce.
suggested balance is to run compound Square 97 front and 97 rear. click here for more information.

These rotors have been documented to last over 60+ events. Cut dry to prevent cutting fluids from contaminating your race pads.
100% CNC machined outer edge for perfect balance.
comes with Aerospace hardware.
lateral runout less than .001" Cut on a $2,000,000 lathe.
you will not find a stronger, longer lasting, slotted rotor anywhere.
Do you actually carry 01 or 11 for Wilwood Dynapro? This application mess is the most frustrating thing i've spent 2 hours trying to figure out, ever. Even more frustrating than the first time i tried to please a woman.

constant drumbeat and think of baseball. good work on woman endeavors.
the 7751 will fit into a dynapro. the top of the pad will overhang the top of the rotor by 1-2mm. this leaves a funny looking tapper. this isn't negative to performance but it is annoying. the dynapro is a strange caliper as it only uses the cotter pins as a pad abutment. to me that's crazy to have a pad be supported vertically by only a pin, but you could drill the pad holes vertically 1-2mm to make the 7751 sit flush with the rotor.
