13 compound is a new generation of ultimate high bite, high friction. This has increased bite, modulation, superior disc conditioning and release characteristics for exceptional control. Ultra-smooth and great for tracks with high grip or high downforce cars. It is the ultimate combination of high bite and infinite control. Typical applications: Ideal use for sprint and severe applications. Heavy, fast cars or high downforce cars where bite at first third of the stop is desired. 13’s wear is on a par with PFC’s legendary 01 compound. It will operate at higher temperatures if called to as it has a very high threshold for fade resistance. 13 has shown, of all the high bite, high torque pads in the market, to have one of the lowest taper wear in a properly-designed race caliper.
