Detailed Product Description

This Dynamite Friction rotor is part of the DFC Geoperformance Rotor - Drilled and Slotted line, which focuses on delivering rotors with enhanced surface geometry for optimized braking efficiency. The drilled and slotted surface helps to evacuate gases, dust, and water from the braking surface, reducing brake fade and maintaining consistent pedal feel. The vented rotor design further aids in heat dissipation, which is critical for maintaining performance during demanding driving conditions.

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 adds an extra layer of protection against environmental factors, helping to maintain rotor integrity over time. With a bolt hole quantity of five and a bolt circle diameter of 120 mm, this rotor is specifically designed to fit select BMW models, ensuring proper fitment and reliable operation.

Compatible Vehicles and Applications

• Compatible with BMW 535i, 545i, 550i, 645Ci, and 650i models
• Ideal for replacing worn or damaged rotors on these vehicles
• Addresses issues such as brake fade, uneven rotor wear, and reduced braking efficiency
• Suitable for drivers seeking improved heat management and braking consistency

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness of 28.4 mm before installation
• Verify bolt hole alignment with vehicle hub using the 120 mm bolt circle diameter
• Clean rotor surface before installation to remove any protective coatings or residues
• Torque lug nuts to manufacturer specifications to avoid rotor warping
