R1 Concepts 830-61003R DFC GeoPerf Drilled & Slotted Brake Rotor

The R1 Concepts 830-61003R DFC GeoPerf Drilled and Slotted Brake Rotor delivers enhanced stopping power and thermal management for demanding street and performance driving applications. Engineered with R1 Concepts' proprietary GeoPerf geometry, this rotor combines precision cross-drilling and strategic slotting to maximize braking efficiency and rotor longevity.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes and machined slots work together to dissipate heat, expel gas and debris, and maintain consistent pad bite under repeated heavy braking
• GeoPerf Geometry: R1 Concepts' precision-engineered slot pattern optimizes pad sweep and bite for predictable, fade-resistant performance
• High-Carbon G3000 Metallurgy: Premium gray iron casting provides superior strength, reduced noise, and excellent thermal stability
• Zinc Dichromate Coating: Corrosion-resistant finish on non-swept surfaces protects against rust and extends rotor life
• Precision Balanced: Computer-balanced to minimize vibration and eliminate brake pedal pulsation
• Direct OEM Replacement: Bolt-on fitment with no modifications required; meets or exceeds OEM specifications

The 830-61003R is a direct-fit replacement rotor designed for performance-minded drivers who want upgraded braking without sacrificing daily drivability. It is fully compatible with OEM and performance brake pad compounds, making it an ideal upgrade for both street and light track use.
