Delivers stopping power for fast road use, autocross, or light track days. Formerly known as Street Performance. Requires some heat to work properly, but less than full track/race pads. Quiet and superior to OEM pads once at operating temperature. Moderate dust, below OEM BMW. Attributes: higher temperature range than OEM, excellent stopping power (torque) at optimum temps, high fade resistance, strong initial bite, smooth actuation, modulation, and release at optimum temps, low-moderate dust, easy on rotors, very good pad wear rates.
