DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on rotors that combine drilled holes and precision slots to improve brake pad bite and heat dissipation. This rotor’s vented design helps reduce brake fade during demanding driving conditions, making it suitable for performance-oriented vehicles like the BMW 330i xDrive and Toyota GR Supra.

Detailed Product Description

This disc brake rotor features a vented construction with a 345 mm outside diameter and a nominal thickness of 24 mm, ensuring durability and consistent braking performance. The drilled and slotted surface enhances water and debris evacuation while improving pad contact. The rotor’s directional design optimizes airflow and cooling. The hat is finished in GeoSpec silver grey and treated with a rust-resistant coating to extend service life. With a bolt hole diameter of 16.7 mm and a 5-bolt pattern on a 112 mm bolt circle diameter, it fits a range of BMW and Toyota models including the 530e xDrive, 840i Gran Coupe, and M240i xDrive.

Applications and Problem Solving

• Reduces brake fade under high-performance or repeated braking conditions
• Improves heat dissipation to prevent rotor warping
• Enhances braking response with directional drilled and slotted surface
• Resists corrosion with rust-resistant coating for longer rotor life
• Compatible with specific BMW and Toyota models requiring a 345 mm vented rotor

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 22.4 mm before installation. Confirm bolt pattern compatibility with your vehicle’s 5-lug, 112 mm bolt circle diameter. Directional rotors must be installed with the correct rotation direction for optimal performance. Clean the rotor surface before mounting to remove any protective coatings or residues.

Quality Assurance

Dynamite Friction manufactures the 830-31130R rotor to meet OEM specifications for fit and function. The rust-resistant coating and precision machining contribute to reliable braking performance. Warranty details should be confirmed with the product documentation or supplier.
