R1 Concepts 830-54243R DFC GeoPerf Drilled & Slotted Brake Rotor

The R1 Concepts 830-54243R DFC GeoPerf Drilled & Slotted Brake Rotor is a premium performance upgrade designed for drivers who demand superior stopping power and thermal management over stock brake components. Part of R1 Concepts' GeoPerf lineup, this rotor combines precision cross-drilling and directional slotting to deliver consistent, fade-resistant braking performance.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce rotor weight and allow heat, gas, and debris to escape, while machined slots continuously clean and deglaze brake pad surfaces for optimal bite
• GeoPerf Technology: R1 Concepts' geometric performance pattern is engineered to maximize pad-to-rotor contact consistency and extend pad life
• Premium G3000 Cast Iron: High-carbon iron construction provides excellent thermal capacity and rotor rigidity, reducing warp and vibration under heavy braking
• Zinc Dichromate Coating: Protective anti-rust coating on non-swept surfaces resists corrosion and maintains a clean appearance
• Precision Balanced: Each rotor is computer-balanced to minimize vibration and pedal pulsation
• Direct OE Replacement: Bolt-on fitment with no modifications required; meets or exceeds OEM specifications

The R1 Concepts DFC GeoPerf rotor is ideal for performance street driving and light track use, offering a meaningful upgrade in braking feel, heat dissipation, and overall rotor longevity compared to standard solid or plain-faced rotors.
