Detailed Product Description

This DFC Geoperformance Rotor - Drilled and Slotted is specifically designed to meet the braking demands of BMW and Mini vehicles, including the BMW 228i Gran Coupe and Mini X1. The vented rotor design improves airflow to reduce heat buildup during braking, while the drilled and slotted surface helps evacuate gases, dust, and water for consistent pad contact. The directional surface ensures proper rotation for optimal performance and wear. The rotor’s plain disc finish combined with a Geospec silver grey hat finish provides corrosion resistance and a clean appearance. With a rust resistant coating, this rotor maintains durability in various driving conditions.

• Fits Mini Cooper Countryman, X1, and X2 models
• Ideal for drivers seeking improved braking response and heat management
• Suitable for replacement of worn or damaged rotors on specified models
• Addresses issues such as brake fade, uneven pad wear, and rotor warping

Installation Notes and Tips

Ensure the rotor is installed with the directional surface rotating correctly according to vehicle specifications. Verify bolt hole alignment with the 5-lug pattern and 112 mm bolt circle diameter. Check rotor thickness before installation; replace if below the discard thickness of 22.4 mm. Proper torque settings on lug nuts are essential to avoid rotor distortion. It is recommended to inspect brake pads and hardware during rotor replacement for optimal braking system performance.
