StopTech wedge-lock floating rotor mounting kit - RACE ONLY 8mm flange, 10 pins

For StopTech PRO Race kits only. Requires AeroHats with special machining and may only be used on kits originally equipped with wedge-lock hardware. Contact Zeckhausen Racing for information about PRO Race kit applications.

Some race cars with advanced ABS may have difficulty with floating rotors. The tiny amount of radial play between rotor hats and float hardware can be detected, during cyclic braking events, as "noise" superimposed on the signal from wheel speed sensors and can trigger unwanted behavior by the ABS. StopTech's patented Wedge Lock drive pin design helps solve this problem by eliminating any radial play between drive pins and hats. When tightened, the 2-piece drive pin expands and firmly locks into place in a specially machined depression in the hat. In addition to solving this ABS issue, the StopTech design extends the life of rotor hats by eliminating wear in the hat's drive pin holes.
