R1 Concepts 830-54302L DFC GeoPerformance Drilled Slotted Brake Rotor - Left

The R1 Concepts 830-54302L is a DFC GeoPerformance Drilled and Slotted Brake Rotor engineered for maximum stopping performance, reliability, and durability. Featuring a combined cross-drilled and slotted design with a premium GEOMET® corrosion-resistant coating, this left-side rotor is a direct-fit upgrade over worn OEM brake rotors.

Key Features:

• Cross-Drilled & Chamfered Holes: Reduces heat buildup on the rotor surface; chamfered edges minimize stress fractures and cracking potential
• Diamond Slots: Continuously sweep brake dust, gas, and road debris from the pad surface to prevent pad glazing and improve bite — especially in wet conditions
• GEOMET® Corrosion Protection Coating: Applied across the entire rotor — including the hub and vane structure — for superior rust resistance; ships dry and is ready to install with no additional cleaning or preparation required
• OE-Matched Vane Configuration: Engineered to replicate the OEM split-core vane design for optimal heat dissipation and rotor balance
• Precision Machined to Tight Tolerances: Each rotor is fine-turned and passes a 100% electronic inspection measuring over 20 attributes to verify OE-spec compliance
• Left-Side Fitment (L): Directional rotor designed specifically for the left/driver-side axle position

The DFC GeoPerformance series delivers a significant upgrade over standard replacement rotors for drivers seeking improved braking response in daily driving, spirited street use, or light performance applications. The GEOMET® finish eliminates the need to wipe down oily shipping coatings, saving time and effort during installation.
