Detailed Product Description

The DFC Geoperformance Rotor - Drilled and Slotted from Dynamite Friction is designed to meet the braking demands of select BMW 5 Series vehicles. This rotor features a vented construction that helps dissipate heat more effectively during braking, reducing the risk of brake fade under heavy use. The directional slotted and drilled surface improves pad bite and helps evacuate gases, dust, and water from the braking surface, maintaining consistent stopping power.

The rotor's plain disc finish combined with a Geospec silver grey hat finish provides corrosion resistance and a clean appearance. The rust resistant coating further protects the rotor from environmental elements, extending its service life. With a nominal thickness of 30 mm and a discard thickness of 28.4 mm, this rotor maintains structural integrity and performance throughout its lifespan.

DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on delivering rotors with enhanced surface designs that improve braking efficiency and heat management. This product line incorporates directional drilled and slotted patterns to optimize pad contact and reduce brake fade, making it suitable for drivers seeking reliable performance on BMW 5 Series models.

Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner braking components
• Enhances heat dissipation to prevent rotor warping
• Protects against rust and corrosion for longer rotor life

Installation Notes and Tips

Ensure the rotor is installed on compatible BMW 5 Series models as specified. Verify the bolt hole pattern (5 lug holes, 14.6 mm diameter, 120 mm bolt circle) matches the vehicle hub. Clean the rotor surface before installation to remove any protective coatings or residues. Proper torque specifications should be followed when securing the rotor to avoid warping or uneven wear.

Quality Assurance

Dynamite Friction manufactures the 830-31062L rotor to meet OEM standards for fitment and performance. The rust resistant coating and vented design contribute to durability and consistent braking. Warranty information is available through the manufacturer and should be consulted for coverage details.
