R1 Concepts 830-31093D GeoPerf Cross-Drilled Slotted Brake Rotor

The R1 Concepts 830-31093D GeoPerf Drilled & Slotted Brake Rotor is a high-performance replacement rotor engineered for drivers who demand superior stopping power and long-term durability. Part of R1 Concepts' GeoPerf series, this rotor combines a cross-drilled and diamond-slotted design to maximize braking efficiency for both everyday street driving and more demanding conditions.

The cross-drilled holes allow heat, gas, and moisture to escape from the rotor surface during braking, reducing fade and maintaining consistent pedal feel. The diamond-slot pattern helps sweep brake dust and debris away from the pad contact surface, promoting even pad wear and improved bite throughout the life of the rotor.

Key Features:

• Cross-Drilled & Diamond-Slotted Design — maximizes heat dissipation, reduces brake fade, and improves wet-weather performance
• Silver Zinc Plated Coating — corrosion-resistant finish protects the hub, hat, and vane structure for improved longevity and appearance
• High-Carbon Casting — provides strength and thermal stability under repeated hard stops
• Direct OE Replacement Fitment — engineered to OE specifications for straightforward installation with no modifications required
• Balanced & Computer-Tested — each rotor is balanced and tested to minimize vibration and runout

The silver zinc coating covers the entire rotor at the time of shipment. During the break-in process, the coating will naturally wear off the braking surface where the pads make contact, while the hub and vane structure retain their protective finish. A proper break-in procedure is recommended to fully seat the pads and optimize rotor performance.
