R1 Concepts 830-46047L Cross-Drilled Slotted Brake Rotor with Geomet Coating

The R1 Concepts 830-46047L is a high-performance cross-drilled and slotted brake rotor featuring advanced Geomet corrosion protection. Manufactured by DFC (Dynamic Friction Company) as part of R1 Concepts' GeoPerf series, this left-side rotor combines precision-engineered drilling and diamond slotting to deliver enhanced stopping power and thermal management.

Key Features:

• Cross-drilled design reduces heat buildup by up to 105°F and enhances ventilation for consistent braking performance
• Diamond slotted pattern removes brake dust and road debris while preventing pad glazing to extend pad and rotor life
• Geomet finish provides superior rust and corrosion protection for longer rotor life and improved appearance
• Constructed from G3000 grade cast iron for excellent thermal stability and durability
• Chamfered and countersunk drill holes prevent cracking and ensure smooth pad bedding
• Built to OEM specifications for direct fit installation without modifications
• Diamond-tipped slot ends serve as wear indicators for rotor replacement

This rotor is ideal for street performance, daily driving, light towing, and spirited driving applications. The Geomet coating is a silver-zinc finish that protects the non-friction surfaces while the braking surface wears naturally during the bedding process. Perfect for drivers seeking a performance upgrade over stock brakes with superior corrosion resistance.
