Abstract
A friction plate is provided including ,a core plate, a core plate first friction facing having a first radius and a first height; and a core plate second friction facing having a second radius differing from the first radius and a second height differing from the first height and having a coefficient of friction differing from a coefficient of friction of the first friction facing, wherein both of the facings are formed from an integral base fiber type friction facing material and wherein the difference in coefficients of friction is due to a percentage of a friction modifying saturant in the facings and wherein there is a groove separating the facings.
