Product Details and Specifications

This disc brake rotor is vented to allow air flow between the rotor surfaces, reducing heat buildup during braking. The directional drilled and slotted surface helps evacuate gases, dust, and water, which can improve braking consistency and reduce brake fade. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18 mm, indicating when replacement is necessary. The rotor’s overall height is 38.6 mm, and it features a 256 mm outside diameter, making it compatible with specific Volkswagen models. The zinc silver hat finish provides rust resistance, while the plain disc finish maintains a clean, functional surface.
