R1 Concepts GeoPerf Drilled Slotted Brake Rotor

The R1 Concepts GeoPerf Drilled and Slotted Brake Rotor line is a performance upgrade over standard OE replacement disc brake rotors. Each rotor is manufactured by Dynamic Friction Company (DFC) and combines cross-drilled holes, precision-cut slots and a corrosion-resistant coating. The result is stronger bite, better heat management and consistent stopping power for street and performance driving.

Key Features:

• Cross-drilled holes: Reduce heat buildup on the rotor surface and help vent gases and debris. The holes are chamfered to help limit the risk of cracking under stress.
• Precision slots: Sweep brake dust and debris from the pad surface. This helps prevent glazing and improves bite, especially in wet conditions.
• Corrosion-resistant coating: A GEOSPEC/Geomet-type protective finish covers the hat and vane structure to fight rust. It is applied dry and wears off the braking surface during pad bed-in.
• OE-grade fit: Built to match OE dimensions and mounting specifications for direct-fit installation without modification.
• Quality control: Rotors undergo electronic inspection of multiple attributes to confirm OE-specification tolerances.
• Durable iron construction: Carbon alloy iron casting supports thermal stability, noise damping and long service life.

GeoPerf rotors suit daily driving, spirited street use and light track applications. Follow the recommended pad bed-in procedure to get the best performance and life from the rotors. They work with R1 Concepts and DFC brake pads.
