SPI continues to offer the best in aftermarket performance
brake pads. When looking for brake pads, a big thing to remember is the coefficient of friction rating for that pad. This is a 2 letter rating system (see graph below). The first letter is the cold temp coefficient rating and the second letter is the hot temp coefficient. The higher the letters, the higher the coefficient of friction.
SPI Semi-Metallic brake pads and shoes are composed of a Non-Asbestos, Semi-Metallic Carbon Kevlar aramid fiber from DuPont and have a DOT rating of “FF”.
Our Full-Metal pads contain Copper, Carbon, Tin, Lead and other metallic elements and have a DOT rating of “FG”.
