Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and aid in heat and gas dissipation. This design helps maintain consistent braking performance under demanding conditions. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life on vehicles such as the Saab 9-5 and Chevrolet Malibu Limited.

Technical Description and Specifications

This vented disc brake rotor features a directional surface with both drilled holes and slots, which work together to reduce brake fade by allowing heat and gases to escape more efficiently. The rotor's nominal thickness is 30 mm, with a discard thickness of 27 mm, ensuring clear service limits for safe operation. The rotor measures 296 mm in outside diameter and 51 mm in overall height, fitting vehicles with a 5-lug bolt pattern and 120 mm bolt circle diameter. The zinc silver hat finish offers rust resistance, while the plain disc finish maintains a clean braking surface.

Compatible Vehicles and Applications

• Buick LaCrosse and Regal models requiring 296 mm vented rotors
• Chevrolet Malibu and Malibu Limited with 5-lug, 120 mm bolt circle
• Saab 9-5 models compatible with drilled and slotted rotors
• Replacement for worn or warped rotors causing brake pulsation
• Upgrading rotors to improve heat dissipation and braking response

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 27 mm before installation. Clean the rotor surface to remove any protective coating or debris. Confirm the 5-lug, 120 mm bolt pattern matches your vehicle’s hub. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.
