Detailed Product Features and Specifications

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver is a vented disc brake rotor measuring 330 mm in outside diameter and 48 mm in overall height. The rotor’s surface is both drilled and slotted, which helps to reduce brake fade by allowing gases and debris to escape while improving water dispersion. The rotor is directional, meaning it is designed to rotate in a specific direction to optimize performance. The hat section features a zinc silver finish that provides corrosion resistance, complemented by an overall rust-resistant coating to extend rotor life.

The rotor thickness is specified with a nominal thickness of 30 mm and a discard thickness of 27 mm, ensuring safe replacement intervals. It includes six bolt holes with a diameter of 16 mm and a bolt circle diameter of 135 mm, matching the stud/lug hole pattern for secure mounting. The center hole diameter of 90.2 mm ensures proper alignment on the hub.
