H Compound - PolyMatrix H is a severe-duty racing compound designed to cope with extremely high heat. Friction rises predictably from high to extra-high as temperature and pedal pressure increase. PolyMatrix H has the highest friction level of any Wilwood pad from 1000°F to 1300°F (and is tied for first with PolyMatrix A from 800°F to 1000°F). Compatible with iron or steel rotors including stainless steel. Recommended for high-horsepower cars and cars with enough downforce to take advantage of the increased friction.
