Carbotech Brake Compounds
The Carbotechâ 1521â is our high performance street compound. The 1521â compound is known for its release and modulation, along with unmatched rotor friendliness. 1521â is also a very low dusting and low noise compound with an excellent initial bite. This compound's excellent linear torque production provides incredible braking force without ABS intervention. Carbotechâ 1521â operating range starts out at ambient and goes up to 800 F (426 C+). 1521â is suitable for ALL street cars, perfect for your tow vehicle or fleet vehicle. Carbotechâ 1521â is NOT recommended for ANY track use.
The AX6â is specifically engineered for Autocross applications. A high torque brake compound delivering reliable and consistent performance over a very wide operating temperature range of 50 F to 1000 F + (10 C to 537 C+). The advanced compound matrix provides an excellent initial bite, high coefficient of friction at lower temperatures along with very progressive brake modulation and release characteristics. Many drivers use the AX6â for street driving as well, even though Carbotechâ doesn't recommend street driving with AX6â due to possible elevated levels of dust and noise. AX6â is NOT recommended as a race compound in most applications.
A high torque brake compound with a wide operating temperature range of 200 F-1250 F+ (93 C to 676 C+). Carbotechâ XP8â is the first of our racing compounds. Good initial bite at race temperatures, high coefficient of friction, excellent modulation and release characteristics. Extremely high fade resistance and very rotor friendly. Perfect for track day use with any tire and can still be driven safely to and from the track. Carbotechâ does NOT recommended XP8â as a daily driven street pad due to elevated levels of dust and noise. Carbotechâ XP8â is a great compound on the front & rear of most open wheel and sports racers.
When Carbotechâ unleashed the XP10â to the general public it immediately gathered multiple regional, divisional, and national championships. The XP10â has a very strong initial bite with a coefficient of friction and rotor friendliness unmatched in the industry. Fade resistance is in excess of 1475 F (801 C). XP10â still maintains the highly praised release, excellent modulation and rotor friendliness that have made all Carbotechâ compounds so successful. Carbotechâ XP10â is not recommended as a daily-driven street pad due to possible elevated levels of dust and noise.
Another highly successful XPâ series compound with an excellent initial bite, torque and fade resistance over and above the XP10â compound. XP12â has temperature range of 250 F to 1850 F+ (121 C to 1010 C+). The XP12â has that excellent Carbotechâ release and modulation that has made all other Carbotechâ compounds so successful. The XP12â is more rotor aggressive than XP10â , but compared to the competition the XP12â is still very rotor friendly. XP12â is NOT recommended for use as a daily driven street pad due to possible elevated levels of dust and noise.
The latest iteration of the highly successful XPâ series of compounds. XP20â is a step up from the highly successful XP16â compound. With an extremely aggressive initial bite, linear torque curve and excellent fade resistance the XP20â is another major step in progression of the highly successful XPâ series line of compounds from Carbotechâ . XP20â has a temperature range of 275 F to 2000 F+ (135 C to 1093 C+). Carbotechâ XP20â maintains our tradition of having the outstanding release and modulation that has made all other Carbotechâ compounds so successful. Carbotechâ XP20â is NOT recommended for use as a daily driven street pad due to possible elevated levels of dust and noise.
XP24â is the pinnacle compound of the extremely successful XPâ Series of compounds engineered by Carbotechâ . This compound is based on the same fundamentals that exist in all other Carbotechâ formulations. XP24â has even more initial bite, more overall bite, and more torque along with the most linear torque curve we have ever offered. The thermal characteristics are of the highest Carbotechâ offers along with one of the highest coefficient of friction ratings offered by anyone in the braking industry. This compound is the longest wearing compound Carbotechâ offers as it was originally engineered for endurance applications at the highest pro racing levels. This revolutionary new compound has been extremely successful with open wheel, closed wheel, sprint and endurance applications. XP24â has a temperature range of 400 F to 2000 F+ (204 C to 1093 C+). Carbotechâ XP24â is NOT recommended for use as a daily driven street pad due to possible elevated levels of dust and noise along with the necessary heat required to work properly.
The RP2â compound was engineered for endurance racing based on our highly successful XPâ Series formulations. RP2â has strong initial bite, a little less modulation than our XP12â , but still maintains the rotor friendliness of our XPâ series compounds. RP2â has great fade resistance with a temperature range of 250 F to 1450 F+ (121 C to 787 C). RP2â is as rotor friendly as our XPâ series compounds. Carbotechâ RP2â is NOT recommended for use as a daily driven street pad due to possible elevated levels of dust and noise.
Carbotechâ 913 Kelated Metallicâ
A D.O.T.-approved high-performance compound for brake shoes on high performance street vehicles and race cars. Carbotechâ Kelated Metallic (CKM) achieves a very high coefficient of friction (approx. 0.48 to 0.50) by taking advantage of a chemical reaction within the friction mass, which creates a tri-alloy metallic film at the liner/drum interface when subjected to heat and pressure. Designed to overcome the shortcomings of other liner materials, CKM is a very versatile and provides excellent braking performance in a wide variety of applications. Excellent wear characteristics and a very high resistance to lock-up under hard braking. Optimal recommended operating temperature range is from ambient to 750 F.
