PFC 11 is progressive so you have more braking torque at the end of a braking zone compared to the beginning of a braking zone. You need to look at the CoF vs. Temperature curve to gain more insight into how a pad performs. PFC11 gives you confidence that they’ll be there at the end of a high-speed long braking zone. They have an extremely high temperature resistance/tolerance.
I’ve used PFC 97, 01, 03, 05, 07, 11, 13, 15 and 39.
01 Compound that set the standard and still is a great compound. It has a high initial bite with high torque that’s pretty stable with temperature, nice release, consistent and predictable at the end of a stop with good modulation. Low pad wear and good rotor conditioning/wear.
03 Compound is similar to 01 but higher initial bite and torque than the 01 Compound. Slight torque rise with temperature which gives you confidence in heavy braking zones. Can over power sticky tires so it requires a more delicate initial application relative to 01 Compound.
05 Compound is my favorite PFC compound. It has a smooth initial bite, and very little torque rise with temperature, excellent release characteristics and great modulation. Although the initial torque application is smooth, it doesn’t mean the torque is low!
07 Compound’s initial bite is higher than 05 compound. CoF rises slightly with temperature but has an extremely high temperature limit. You can beat the crap out of this pad and it will never give up.
11 Compound is my 2nd favorite PFC compound. It was derived from the 01 Compound. It has improved bite, improved modulation and exit release characteristics. Lower initial torque but rising CoF with temperature so torque increases throughout the braking event. Excellent pad wear and phenomenal rotor conditioning/wear. Best compound for cars without downforce.
13 Compound has very high initial bite and very high CoF with temperature so extremely fade resistant. Smooth pad with great release characteristics, superior control and modulation. Pad wear matches 01 Compound but with good rotor conditioning/wear. Need extremely sticky tire and/or functional aero.
15 Compound is similar to 13 Compound but with a lower CoF with temperature so easier to modulate. Good pad wear and improved rotor conditioning/wear compared to 13 Compound.
39 Compound is similar to 13 except for higher torque in the last 1/3rd of the braking event. Very high initial bite but predictable/consistent due to its high temperature resistance. Requires a smooth initial brake application to prevent over powering of the tires. Functional aero highly recommended.
I’ve also used Hawk DTC70, Hawk DTC60, Cobalt XR1 and Cobalt XR2, and CT XP12, XP18 & XP20. Not a fan of Hawk DTC compounds. Cobalt XR1 is similar to PFC 05 and XR2 is similar to PFC 01. CT pads are my backup pads if I’m unable to get PFC compounds I’m looking for. CT was the first company to make custom pads for the ZR31 calipers.
