Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Silver from Dynamite Friction is designed specifically for Nissan 720, D21, and Pickup vehicles, ensuring a precise fit and reliable braking performance. This rotor features a vented design that helps dissipate heat more effectively during braking, reducing the risk of brake fade. The directional surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the rotor surface, improving pad bite and overall braking consistency.

The rotor’s hat is finished with a zinc silver coating to resist corrosion, while the disc surface has a plain finish with an additional rust-resistant coating to extend the rotor’s service life. With six bolt holes and a bolt circle diameter of 103 mm, this rotor matches the factory specifications for the intended Nissan models. The nominal thickness of 22 mm and discard thickness of 20 mm provide clear guidelines for maintenance and replacement.
