Dynamic Friction 4822-31178 DFC GeoSpec Coated Plain Brake Rotor

The Dynamic Friction Company (DFC) 4822-31178 is a GeoSpec coated plain brake rotor engineered to deliver consistent, reliable stopping performance as a direct OEM replacement. Manufactured to precise dimensional tolerances, this rotor installs without modification and restores factory braking feel and response.

DFC's GeoSpec coating provides full corrosion protection across the entire rotor surface — including the hat, vanes, and edges — preventing rust bloom and extending service life beyond that of uncoated rotors. The rotor arrives ready to install with no need for additional prep or cleaning of non-friction surfaces.

Key Features:

• Plain (non-drilled, non-slotted) rotor design for quiet, smooth everyday street performance
• GeoSpec full-surface corrosion-resistant coating prevents premature rust and surface deterioration
• Manufactured to OEM geometry for precise fit and function
• Balanced to minimize vibration and pedal pulsation
• High-carbon grey iron construction for improved thermal capacity and reduced noise
• Direct bolt-on replacement — no machining or modification required
• Designed for use with OEM-style or performance brake pads

The DFC GeoSpec rotor is an ideal choice for daily drivers seeking a long-lasting, corrosion-resistant brake rotor that meets or exceeds original equipment standards. Pair with DFC compatible brake pads for a complete brake service solution.
