R1 Concepts 830-65012L DFC GeoPerf Drilled & Slotted Brake Rotor

The R1 Concepts 830-65012L DFC GeoPerf is a premium drilled and slotted performance brake rotor engineered for drivers who demand superior stopping power and thermal management. This left-side rotor combines precision manufacturing with high-carbon iron construction to deliver consistent, fade-resistant braking performance under both daily driving and spirited conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce unsprung weight and allow heat and gas to escape, while slots continuously clean the brake pad surface for maximum bite and improved bite
• High-Carbon Iron Construction: Reduces noise, vibration, and harshness (NVH) while improving overall durability and rotor longevity
• Zinc Dichromate Coating: Protects the rotor hat and non-swept areas from corrosion and rust during initial break-in and storage
• Precision Balancing: Each rotor is precision balanced to minimize vibration and pedal pulsation
• Direct OE Replacement: Bolt-on fitment with no modifications required for a hassle-free installation
• GeoPerf Series: Part of R1 Concepts' performance-oriented rotor lineup, designed for enhanced braking performance over standard OEM rotors

The R1 Concepts GeoPerf drilled and slotted rotors are an excellent upgrade for drivers seeking improved brake response and thermal dissipation. Sold individually — this listing is for the left-side rotor only. Pair with quality brake pads for optimal system performance.
