R1 Concepts 830-27047L DFC GeoPerf Drilled & Slotted Brake Rotor

The R1 Concepts 830-27047L DFC GeoPerf Drilled and Slotted Brake Rotor is a high-performance upgrade designed for drivers who demand superior stopping power and thermal management. Part of R1 Concepts' GeoPerf (Geometric Performance) series, this rotor combines precision drilled holes and milled slots to deliver enhanced braking performance over standard OEM rotors.

The drilled and slotted surface pattern serves a dual purpose: the cross-drilled holes reduce rotor weight and dissipate heat rapidly, while the slots continuously sweep the brake pad surface clean of gases, dust, and debris. The result is consistent, fade-resistant braking performance under both everyday driving and demanding conditions.

Key Features:

• Drilled & Slotted Design – Improves heat dissipation, reduces brake fade, and extends pad life
• GeoPerf Series – Precision-engineered geometric slot and drill pattern for optimized airflow and cooling
• Premium Grade Iron – High-carbon iron alloy construction for durability and consistent friction performance
• Zinc Dichromate Coating – Corrosion-resistant finish on non-swept areas to prevent rust and improve appearance
• Direct OEM Replacement – Bolt-on fitment with no modifications required
• Computer Balanced – Minimizes vibration and pedal pulsation for a smooth, confident braking feel
• Left Side Application (L) – Designed specifically for the driver-side (left) position

R1 Concepts rotors are manufactured to strict quality standards and are a direct replacement for the original equipment rotor. Whether upgrading for performance driving or replacing worn rotors, the 830-27047L delivers reliable, fade-free stopping power with a premium look to match.
