• Disc brake rotor with drilled and slotted surface for improved heat management
• Directional brake surface optimized for specific vehicle fitment
• 330 mm outside diameter suitable for multiple BMW and Toyota models
• Zinc silver hat finish with rust-resistant coating for durability
• Plain disc finish with a discard thickness of 18.4 mm

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver features a 330 mm outside diameter and a discard thickness of 18.4 mm, ensuring compatibility with various BMW and Toyota vehicles including the BMW 230i, 330i, 430i, 530i series, and Toyota GR Supra among others. The rotor’s surface is both drilled and slotted, which helps to reduce brake fade by allowing gases and debris to escape, while also improving wet weather braking performance. The directional design of the brake surface ensures optimal contact and braking efficiency when installed correctly.

The rotor’s hat is finished in zinc silver, providing corrosion resistance and extending the rotor’s service life. Additionally, the entire rotor is coated with a rust-resistant layer to protect against environmental wear. The plain disc finish complements the drilled and slotted surface, maintaining structural integrity and consistent braking feel.
