R1 Concepts 830-54294R GeoPerf Drilled Slotted Brake Rotor

The R1 Concepts 830-54294R GeoPerf Drilled and Slotted Brake Rotor is a high-performance disc brake rotor engineered for drivers who demand superior stopping power, durability, and corrosion resistance. Built to OEM specifications, this rotor installs with no modifications required and delivers a meaningful upgrade over factory brake components.

Featuring R1 Concepts' signature GEOMET® protective finish, this rotor provides industry-leading corrosion protection that outperforms standard zinc or e-coat finishes, significantly extending the life of the rotor and maintaining a clean, professional appearance. The GEOMET coating also reduces installation time by eliminating the need for pre-cleaning before fitment.

Key Features:

• Cross-Drilled & Diamond Slotted Design: Precision-drilled holes are chamfered and countersunk to prevent cracking and promote a smoother bed-in process, while diamond slots remove brake dust and road debris, prevent pad glazing, and extend pad life
• G3000 Grade Cast Iron Construction: High-carbon alloy iron formula enhances thermal stability, reduces brake fade, and minimizes noise and vibration under demanding conditions
• GEOMET® Corrosion Protection Finish: Superior rust protection that keeps the hub, vanes, and non-contact surfaces protected for the life of the rotor
• Heat Dissipation: Cross-drilled holes reduce rotor surface heat buildup by up to 105°F, improving consistent braking performance during repeated stops
• OEM-Compatible Fitment: Machined to OEM dimensions for a direct, bolt-on replacement with no modifications needed
• Wear Indicator: Diamond slot tips serve as a built-in rotor wear indicator — when the tips wear away, it signals time for replacement

Suitable for daily street driving, light track use, towing, hauling, and off-road applications, the R1 Concepts GeoPerf rotor is an excellent performance upgrade over standard OEM rotors. A proper break-in (bedding) procedure is recommended upon installation to achieve optimal braking performance.
