Brand: Wilwood Engineering
Fits Alcon CAR22 calipers, Wilwood IR-GT calipers (Wilwood shape 7616), and several Brembo calipers (X2.040.01/04, X9.066.91/94, X94.75.11/14, and XA4.10.01/04 - Brembo pad shape B08). These calipers were used on some F3 and Formula Atlantic cars including the Swift 008 and 014a. Pads measure 16mm (0.62") thick including backing plate. Sold in axle sets (one box fills 2 calipers).
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. 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.
