R1 Concepts 830-20041R GeoPerf Drilled Slotted Brake Rotor with Geomet Coating

The R1 Concepts 830-20041R is a GeoPerf series cross-drilled and diamond-slotted brake rotor featuring a proprietary GEOMET® anti-corrosion coating. Built to G3000 grade cast iron standards with OEM-compatible dimensions, this rotor delivers a meaningful performance upgrade over factory brakes without requiring any vehicle modifications.

Key Features:

• Cross-Drilled Design: Precision-drilled holes with countersunk chamfering reduce rotor surface heat by up to 105°F, enhance airflow, and minimize the risk of cracking under repeated hard stops
• Diamond Slot Technology: Diamond-slotted grooves sweep brake dust and road debris from the pad-rotor interface, prevent pad glazing, and extend the service life of both the pad and rotor — with diamond-tipped slot ends serving as a built-in wear indicator
• GEOMET® Anti-Corrosion Coating: A proprietary finish that provides superior, long-lasting rust protection across the entire rotor surface, including the hub and inner vane structure, and reduces installation time
• G3000 Grade Cast Iron: High-quality iron grade engineered for thermal stability, consistent stopping power, strength, and dimensional accuracy
• OEM-Compatible Fitment: Engineered to OEM specifications — no modifications required for direct installation
• Mill Balanced: Precision mill-balanced to minimize vibration and rotor feedback through the brake pedal

Break-In Note: New rotors arrive fully coated with the GEOMET® finish. During the initial bedding process, the coating on the braking surface — where the pads contact the rotor — will gradually wear away. The hub and inner vane areas will remain coated for continued corrosion protection. Always follow R1 Concepts' recommended brake bedding procedure after installation.

The R1 Concepts 830-20041R GeoPerf rotor is well-suited for street performance driving, daily use, and light track or spirited driving applications where improved heat dissipation, pad life, and corrosion resistance are priorities.
