Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Silver from Dynamite Friction is specifically designed for BMW X5 and X6 models, providing reliable braking performance under demanding conditions. The rotor’s vented construction allows for efficient heat dissipation, reducing the risk of brake fade during extended use. The directional surface features both drilled holes and slots, which help to evacuate gases, dust, and water from the braking surface, improving pad contact and braking consistency.

With a nominal thickness of 30 mm and a discard thickness of 28.4 mm, this rotor maintains structural integrity and performance throughout its service life. The zinc silver hat finish combined with a rust-resistant coating protects against corrosion, extending the rotor’s durability. The rotor’s 348 mm outside diameter and 62.2 mm height ensure proper fitment and compatibility with the specified BMW models.
