R1 Concepts 830-63176R GeoPerf Drilled Slotted Brake Rotor

The R1 Concepts 830-63176R GeoPerf Drilled and Slotted Brake Rotor is a high-performance replacement rotor engineered for drivers who demand more from their braking system. Featuring a cross-drilled and diamond-slotted surface design, this rotor delivers improved stopping power, enhanced heat dissipation, and consistent performance whether you're commuting daily or pushing the limits on a track.

The GeoPerf rotor is treated with a premium Geomet protective coating — a corrosion-resistant finish applied to the hat, vanes, and non-contact surfaces to guard against rust and extend rotor life. The coating on the braking surface will naturally wear off during the break-in period as pads seat against the rotor, which is normal and expected.

Key Features:

• Cross-drilled holes promote rapid heat dissipation and reduce the risk of brake fade under heavy use
• Diamond-slotted surface continuously sweeps away gas, dust, and debris for consistent pad bite and improved wet-weather performance
• Geomet corrosion-resistant coating protects non-braking surfaces from rust for a cleaner, longer-lasting appearance
• Meets or exceeds OE specifications for a direct-fit, no-modification installation
• Engineered for street driving, performance driving, and light towing/hauling applications
• Manufactured by R1 Concepts — a Los Angeles-based leader in aftermarket braking systems

A proper break-in (bed-in) procedure is recommended after installation to ensure optimal pad transfer and rotor performance. Follow R1 Concepts' published break-in guidelines for best results.
