This vented disc brake rotor features a directional, slotted and drilled surface designed to enhance heat dissipation and maintain consistent stopping power under demanding conditions.

• Compatible with Mazda RX-8 models
• Directional slotted and drilled surface for improved brake cooling
• Vented rotor design to reduce heat buildup
• Black zinc-coated hat finish for corrosion resistance
• Rust resistant coating on rotor surface
• 5 bolt holes with 114.3 mm bolt circle diameter
• Nominal thickness of 24 mm and discard thickness of 22 mm
• Outside diameter of 323 mm and overall height of 44.9 mm

Detailed Product Features and Specifications

This Dynamite Friction rotor is a vented disc type, which helps dissipate heat more effectively than solid rotors, reducing the risk of brake fade during extended use. The rotor surface is both drilled and slotted, providing channels for gas and dust to escape, which improves braking consistency and pad bite. The directional design ensures optimal performance when installed correctly according to the rotation direction.

The rotor’s hat is finished with a zinc black coating, enhancing corrosion resistance and durability, while the rotor surface has a rust-resistant coating to extend service life. With a nominal thickness of 24 mm and a discard thickness of 22 mm, this rotor maintains structural integrity and safety standards. The 5-bolt hole pattern with a 114.3 mm bolt circle diameter and 12.9 mm stud hole diameter matches the Mazda RX-8 specifications precisely.
