• Overall outside diameter of 294 mm and height of 75 mm

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a vented rotor design that promotes efficient heat dissipation, reducing the risk of brake fade during extended use. The rotor’s surface is both drilled and slotted, which helps to evacuate gases, dust, and water from the braking surface, improving pad bite and overall braking consistency. The directional surface pattern is optimized for the BMW Z4’s braking system, ensuring proper rotation and performance.

The rotor measures 294 mm in outside diameter and 75 mm in height, with a nominal thickness of 19 mm and a discard thickness of 17.4 mm, indicating when replacement is necessary. The zinc silver coating on the hat provides rust resistance, extending the rotor’s service life. The 5-bolt hole configuration with a 14.2 mm diameter and 120 mm bolt circle diameter matches the BMW Z4’s hub specifications for a secure fit.
