Dynamic Friction 4002-63156 GeoSpec Coated Drilled Disc Brake Rotor

The Dynamic Friction Company 4002-63156 is a GeoSpec Coated drilled disc brake rotor engineered for reliable, consistent stopping performance. Designed as a direct OE-style replacement, this rotor installs without modification and restores proper braking function to your vehicle.

GeoSpec Coating is Dynamic Friction's proprietary anti-corrosion treatment applied to all non-friction surfaces of the rotor. This coating protects against rust and oxidation, keeping the rotor looking clean and performing reliably throughout its service life — even in wet or harsh conditions.

Key Features:

• Drilled design promotes improved heat dissipation and helps evacuate gas and water from the rotor surface for consistent brake pad contact
• GeoSpec anti-corrosion coating applied to hat, edges, and non-friction surfaces to prevent rust and surface oxidation
• OE-matched geometry ensures proper fit, alignment, and rotor runout within factory tolerances
• Precision machined for smooth, vibration-free braking with minimal pedal pulsation
• Direct bolt-on replacement — no modifications required for installation
• Manufactured to meet or exceed OEM specifications for thickness, hardness, and balance

Dynamic Friction Company is a leading supplier of brake components to professional technicians and performance enthusiasts alike. The 4002-63156 GeoSpec Coated Drilled Rotor is a high-quality upgrade or replacement option that combines corrosion resistance with improved thermal performance in a clean, drilled finish.
