The RS2.1 friction material offers even lower mu levels compared to RS2. RS2.1 offers a digressive mu profile where the friction coefficient reduces with temperature and pressure. The digressive mu profile allows the driver to brake with confidence without engaging the rear ABS under lockup. The RS2.1 compound should be used in the rear if severe ABS engagement or rear axle lockup is experienced with the RS2 compound. RS2.1 has improved wear resistance over the RS2 compound making it suitable for endurance races when paired with the RS1 or RS1.1 materials.
