Dynamic Friction 4522-63152 GeoSpec Coated Cross-Drilled Disc Brake Rotor

The Dynamic Friction Company (DFC) 4522-63152 is a GeoSpec Coated cross-drilled disc brake rotor engineered as a direct OE replacement with enhanced corrosion resistance and improved thermal performance. Featuring DFC's proprietary GeoSpec silver-gray coating, this rotor fights rust far more effectively than conventional paint or zinc coatings — and ships dry, ready to install with no additional prep required.

Cast from premium G3000/G11H18 gray iron, the rotor is CNC-machined to the tightest tolerances in the industry and 100% precision mill-balanced to eliminate vibration at any speed. The cross-drilled hole pattern evacuates heat and gases that build up between the rotor face and brake pad, promoting consistent braking performance and reducing fade under demanding conditions. The non-directional rotor surface promotes faster pad break-in and smoother stops from the first application.

Key Features:

• GeoSpec Coating: Durable silver-gray finish provides superior rust protection versus conventional paint or zinc coatings
• Ships Dry, Ready to Install: No cleaning or degreasing required — coating safely sweeps away during break-in
• Premium G3000/G11H18 Iron Casting: Optimized for strength, stability, and long service life
• Cross-Drilled Surface: Reduces heat buildup and outgassing for more consistent braking performance
• CNC-Machined to Tight Tolerances: Ensures precise fit and smooth, vibration-free braking
• 100% Precision Mill-Balanced: Zero vibration at any speed
• Non-Directional Finish: Promotes faster break-in and smoother initial stops
• OE Vane Configuration: Maintains proper and maximum heat dissipation
• OEM Part Number Cross-Reference: 0004212312, 4212312
• Outside Diameter: 360 mm | Nominal Thickness: 36 mm | 5-Lug, 112mm Bolt Circle

Designed to meet the same form, fit, and function as the original equipment rotor, the DFC 4522-63152 passes a 100% electronic quality inspection measuring over 20 attributes before leaving the facility — ensuring a trouble-free installation and dependable stopping performance.
