Titanium Nose Pistons



StopTech Racing’s Titanium piston nose assemblies are designed for the punishing world of motorsport. The patented design provides a carefully engineered thermal barrier for optimal brake system performance, keeping excess heat from radiating through the backing plates. The tops of the titanium noses are castellated, reducing their contact area, and simultaneously reducing conduction while allowing better airflow for reduced heat convection as well.

 The patented design of the StopTech Titanium piston nose assemblies uses an aluminum piston body that matches the expansion rate of the aluminum calipers, and a mushrooming low-profile titanium nose that maximizes coverage as well as useable pad thickness.

 These precision-machined StopTech titanium piston nose assemblies work with existing StopTech calipers that utilize dust boot grooves, providing maximum thermal protection that surpasses that of flexible stamped shims used in other competitive systems.
