• Overall height and height of 64.8 mm, outside diameter of 288 mm

Detailed Product Features and Specifications

This Dynamite Friction rotor features a solid disc design with a directional surface that is both drilled and slotted. The drilled holes and slots help reduce brake fade by allowing gases and heat to escape more efficiently during braking. The rotor’s plain disc finish combined with a zinc silver hat finish provides corrosion resistance, supported further by a rust-resistant coating to extend rotor life. The rotor measures 288 mm in outside diameter with a nominal thickness of 12 mm and a discard thickness of 10 mm, ensuring it meets Volvo’s specifications for safe operation. The five bolt holes, each 16.5 mm in diameter, are arranged on a 108 mm bolt circle diameter, matching the stud/lug hole pattern for a secure fit. The center hole diameter is 68 mm, and the overall height is 64.8 mm, making it compatible with the specified Volvo models.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant finish.
