Dynamic Friction 4522-63123 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4522-63123 is a GeoSpec fully coated plain brake rotor engineered as a direct OEM replacement. Featuring DFC's proprietary GeoSpec coating technology, this rotor delivers superior corrosion resistance and a clean, ready-to-install finish straight out of the box.

GeoSpec Coating Technology:

• Specially formulated paint coating produces a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings
• Complete inside-and-out coating protects the rotor before and after installation
• Coating is safely swept away by friction material during break-in with no harmful effects on braking performance
• Shipped dry and ready to install — no cleaning or pre-treatment required

Premium OEM-Grade Construction:

• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and durability
• OE vane configuration duplicated precisely for maximum heat dissipation
• CNC-machined to the tightest tolerances for consistent, reliable performance
• 100% precision mill-balanced for smooth, vibration-free stopping at any speed
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter stops
• 100% inspected to verify all critical attributes meet OE specifications

Plain / Blank Rotor Style: The 4522-63123 features a smooth, plain braking surface ideal for everyday street driving, offering quiet operation and even pad wear. This rotor is engineered to match the same form, fit, and function as the original equipment rotor it replaces.

The DFC GeoSpec rotor program covers more than 1,400 SKUs across a comprehensive range of foreign and domestic passenger car and light truck applications, making it one of the most complete coated rotor programs in the industry.
