• Directional slotted and drilled surface for improved brake cooling
• Vented rotor design to reduce heat buildup
• Nominal thickness of 30 mm with a discard thickness of 27 mm
• Zinc silver hat finish with rust-resistant coating
• Five bolt holes with 14.2 mm diameter and 115 mm bolt circle diameter
• Overall diameter of 321 mm and height of 61.2 mm

Detailed Product Features and Specifications

This Dynamite Friction DFC Brake Rotor is constructed with a vented design that allows air to flow between the rotor surfaces, helping to dissipate heat more effectively during braking. The rotor’s surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving brake pad bite and reducing the risk of brake fade. The directional brake surface ensures optimal performance when installed in the correct orientation.

The rotor’s nominal thickness is 30 mm, with a discard thickness of 27 mm, indicating when replacement is necessary to maintain safe braking. The rotor features a plain disc finish combined with a zinc silver hat finish that includes a rust-resistant coating to protect against corrosion and extend service life. The five bolt holes and stud/lug holes, each with a diameter of 14.2 mm and a bolt circle diameter of 115 mm, ensure proper fitment on compatible Cadillac models.
