Detailed Product Features and Specifications

This Dynamite Friction rotor is designed with a vented construction to improve heat dissipation during braking, reducing the risk of brake fade. The rotor’s surface is both drilled and slotted, which helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and performance. The directional surface pattern is engineered to optimize braking efficiency and reduce noise.

The rotor measures 330 mm in outside diameter with an overall height of 74.8 mm. It has a nominal thickness of 28 mm and a discard thickness of 26 mm, ensuring a long service life while maintaining safety standards. The hat section features a Geospec silver grey finish that provides corrosion resistance, complemented by an additional rust resistant coating on the rotor surface.

Mounting is secured with five bolt holes arranged on a 130 mm bolt circle diameter, compatible with the specified vehicle models. The center hole diameter is 85 mm, and the stud/lug hole diameter is 15.2 mm, matching factory specifications for a direct fit.
