Detailed Product Description

The 830-31062R rotor from Dynamite Friction’s DFC Geoperformance Rotor - Drilled and Slotted line is designed to meet the specific braking demands of select BMW vehicles. Its vented construction improves heat dissipation during braking, reducing the risk of brake fade under heavy use. The drilled and slotted surface enhances water and gas evacuation, maintaining consistent brake pad contact and improving stopping power. The rotor’s directional design ensures optimal performance when installed correctly, while the Geospec silver grey hat finish provides corrosion resistance and a clean appearance. With a nominal thickness of 30 mm and a discard thickness of 28.4 mm, this rotor maintains structural integrity and safety throughout its service life.

Applications and Problem Solving

• Compatible with BMW 525i, 525xi, 528i, 528i xDrive, 528xi, 530i, 530xi, 535i xDrive, and 535xi models
• Addresses brake fade caused by excessive heat buildup
• Reduces rotor warping and cracking through vented design
• Improves braking performance in wet conditions with drilled and slotted surface
• Prevents rust and corrosion with protective coating

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction for optimal performance. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt pattern and 120 mm bolt circle diameter. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 28.4 mm. Proper torque specifications should be followed when securing the rotor to avoid warping.
