RS-14-Black - This is a high friction value ceramic compound with very good modulation, high fade resistance, low heat conductivity, and a good wear rate up to a constant temperature of 650 degrees Celsius (1202 degrees Fahrenheit). It is kind on discs, (with visible grooving, but no tendency to crack discs). Applications: Super Touring, WSC, Trans Am, and Rallye.

RS-44-Orange - This compound has a very good fade resistance and a higher average friction value than the RS 4-2. It is rotor friendly with a very foreseeable non-aggressive friction behavior (stable torque). It is a very good rear compound for Touring Car applications in combination with RS 14 front pads. It’s main application is Porsche 911 racing. It is used on either Short Track or Long Distance; also for front and rear axles.
