Detailed Product Features and Specifications

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC product line, which focuses on delivering reliable braking components with enhanced surface designs. This rotor combines drilled holes and slots on the braking surface to improve water and gas evacuation, reducing brake fade during demanding driving conditions. The vented rotor design further aids in heat dissipation, maintaining consistent braking performance.

Constructed with a plain disc finish and a zinc silver hat finish, this rotor offers corrosion resistance thanks to its rust-resistant coating. The rotor measures 299 mm in outside diameter with an overall height of 71.3 mm, fitting precisely on Porsche 928 and 944 vehicles. The 5-bolt hole pattern with a 130 mm bolt circle diameter ensures secure mounting, while the directional surface design aligns with the rotor's rotation for optimal braking efficiency.

Applications and Problem Solving

• Replacement rotor for worn or warped brake discs on Porsche 928 and 944
• Improves heat dissipation to reduce brake fade during spirited driving
• Enhances water and debris evacuation for consistent braking in wet conditions
• Restores braking performance compromised by surface damage or corrosion
• Maintains proper rotor thickness to ensure safe braking operation

Installation Notes and Tips

When installing the 631-02020R rotor, ensure the directional surface is oriented correctly according to the vehicle’s rotation. Verify that the rotor thickness is above the discard thickness of 22 mm before installation. Clean the hub surface and mounting points to prevent uneven rotor seating. Use proper torque specifications for the 5 lug bolts with a 130 mm bolt circle diameter to secure the rotor firmly.
