Wilwood Polymatrix Q Brake Pads Calipers: Wilwood DynaPro, NDL (Modified for -SI Calipers)

PolyMatrix ''Q'' is a ceramic enhanced formula developed for ultra quiet performance for custom street and hot rod applications. This revolutionary new friction material has improved stopping power over all types of OE pads, with quieter stopping and lower dust than any non-asbestos, organic or metallic based compounds. The ''Q'' compound has smooth engagement, long service life, quick recovery, and high fade resistance. PolyMatrix ''Q'' is available in the common pad shapes used in most after market performance calipers and several popular OE models. The patented Nucap Retention System is employed to retain the friction material onto the steel backing plates. NRS has been proven to provide the strongest method of retaining the friction material on the backing plate. There are no bonding adhesives to break down in high heat conditions and no rivets to loosen after repeated high torque stops. In addition, this 100% retention method eliminates any possibility of high frequency vibration. PolyMatrix racing pads feature this unique retention system that guarantees exceptional durability with quiet operation.
