Dynamic Friction 4522-63131 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4522-63131 is a GeoSpec fully coated plain (blank) disc brake rotor engineered as a direct OE replacement. Featuring DFC's proprietary GeoSpec coating, this rotor delivers a durable, attractive silver-gray finish that provides superior corrosion resistance compared to conventional paint or zinc coatings — protecting the rotor before, during, and after installation.

Key Features:

• Fully Coated Design: GeoSpec coating is applied inside and out, offering complete protection from the elements without contaminating friction or braking surfaces
• Premium Iron Casting: Engineered with G3000/G11H18 iron castings for exceptional strength, stability, and long-term durability
• OE Vane Configuration: Original Equipment vane geometry ensures proper and maximum heat dissipation for consistent braking performance
• CNC-Machined Precision: Processed to the tightest tolerances available, with a non-directional finish to promote a faster, more even brake pad bed-in and quieter stops
• 100% Mill-Balanced: All vented rotors are electronically mill-balanced for smooth, vibration-free stopping at any speed
• Ready to Install: Shipped dry with no oil coating — no pre-degreasing or additional preparation required, saving time and money during installation
• 100% Inspected: Every rotor passes a full inspection station verifying all critical attributes meet OE specifications before shipping

The DFC GeoSpec program covers a broad range of domestic and import passenger car and light truck applications. This plain-style rotor is ideal for daily commuting, performance street driving, and towing applications, delivering reliable OE-level stopping power with enhanced corrosion protection.
