Description

StopTech Aero-Rotor replacement friction rings feature the patented Aero-Rotor 2-piece vane design. They are available drilled or slotted in bare iron, which is best for use in the performance motorsports environment and provides the most consistency as a friction surface. They're also available with zinc plating, which is best for corrosive environments such as those where road salt is used. All StopTech products are machined to ISO standards.
