The primary considerations for pad selection are temperature range and overall friction value.
The pads must maintain the proper amount of friction for stopping power within the temperatures realized on the track during the event.
Overall wear rate must also be considered.
For most asphalt and road race applications, compounds in the high temperature ranges over 1000°F are usually necessary.
Dirt track, drag race, and street performance applications typically operate at temperatures between 500° and 1000°F.
Keep in mind that these are general ranges and not absolute values.
Many factors and unforeseen influences can affect brake temperatures.
The best indicator for pad selection will always be on track performance.
If pad fade (friction loss) due to overheating occurs, improved cooling, a heavier rotor, or a higher temperature range pad may all become necessary.
Race ONLY compound used in ARCA, ASA, ALMS, Grand-AM, NASCAR, REMAX, SCCA, USAC, and other severe duty oval, road course, and off-road series that require an aggressive response and durability in the highest temperature ranges.
Lightweight sprints and club sport racers using steel plate rotors require fast response at low temperatures with resistance to fade during periodic or temporary high temperature spikes.
Immediate cold response with highest friction values at all temperatures is a characteristic.
Severe duty use on oval tracks, road courses, and other applications requires immediate high torque response.
Long wear rate for sustained high heat braking is noted.
Compatible with all iron and steel rotors.
