Technical Specifications and Features

This disc brake rotor has a nominal thickness of 22 mm and a discard thickness of 20 mm, ensuring a long service life before replacement is necessary. The rotor’s vented design allows air to flow between the rotor faces, reducing the risk of brake fade during aggressive driving. The directional slotted and drilled surface helps channel away brake dust and gases, maintaining consistent braking performance. The zinc black hat finish combined with a rust-resistant coating protects against corrosion, especially in humid or wet environments.

Applications and Problem Solving

• Improves braking performance on Fiat 124 Spider and Mazda MX-5 Miata
• Reduces brake fade during spirited driving or track use
• Minimizes rotor warping caused by excessive heat
• Helps prevent rust and corrosion on rotor surfaces
• Maintains consistent brake pad contact and bite

Installation Notes and Tips

Ensure the rotor is installed on vehicles with a 4-bolt pattern and a 100 mm bolt circle diameter. Verify the center hole diameter of 55 mm matches the hub for proper fitment. It is recommended to inspect brake pads and hardware during installation and replace if worn. Proper torque specifications should be followed to avoid rotor distortion.
