R1 Concepts 830-67058L Drilled Slotted Performance Brake Rotor

The R1 Concepts 830-67058L is a high-performance drilled and slotted brake rotor engineered to deliver superior stopping power and durability for demanding driving conditions. Part of the DFC GEOPERF series, this rotor features both cross-drilled holes and diamond slot technology to maximize braking performance while extending component life.

Advanced Design Features:

• Cross-drilled holes reduce rotor temperature by up to 105°F, improving heat dissipation and preventing brake fade
• Diamond slot technology removes brake dust and road debris while preventing pad glazing
• Precision countersunk holes are chamfered to reduce the potential for cracking under stress
• Mill-balanced construction minimizes vibration and ensures smooth, quiet operation

Superior Corrosion Protection:

• GEOMET anti-corrosion coating provides long-lasting rust protection on all non-friction surfaces
• Zinc-aluminum flake coating dramatically extends rotor life and maintains appearance
• Coating wears away naturally from friction surfaces during break-in while protecting hub and vanes

Construction & Materials:

• Manufactured from G3000 grade cast iron for optimal strength, stability, and durability
• Symmetric split-core casting technology enhances heat dissipation and structural integrity
• Built to OEM specifications for direct fitment with no modifications required
• Non-directional finish promotes faster, more even brake pad bed-in

Ideal for street performance, light track use, towing, hauling, and off-road applications. The diamond-tipped slot ends serve as a wear indicator—when the tips disappear, rotor replacement is necessary. This is a left-side (driver side) rotor as indicated by the "L" suffix in the part number.
