Dynamic Friction 4524-11012 GeoSpec Coated Plain Disc Brake Rotor - OE Replacement

The Dynamic Friction 4524-11012 is a GeoSpec fully coated plain disc brake rotor engineered as a direct OE replacement. DFC's GeoSpec coating forms a durable, attractive silver-gray finish that provides superior corrosion resistance compared to conventional paint or zinc coatings — processed dry, shipped dry, and ready to install with no pre-degreasing or additional preparation required.

Each rotor is CNC-machined at state-of-the-art facilities to the tightest tolerances available, then finished with a non-directional surface to promote faster, more even brake pad bed-in and quieter, smoother stops. All vented rotors undergo a 100% electronic mill-balance inspection and are corrected as needed to ensure zero vibration at any speed. After machining, every rotor passes a 100% quality inspection measuring all critical attributes to confirm full OE specification compliance.

Key Features:

• GeoSpec Coating: Patented silver-gray finish withstands 400+ hours of salt spray testing — superior to zinc or conventional paint coatings
• Premium Iron Casting: Engineered with G3000/G11H18 iron for outstanding strength, stability, and long-term durability
• OE Vane Configuration: Matches original equipment vane design for proper and maximum heat dissipation
• CNC-Machined Precision: Processed to tightest market tolerances with Disc Thickness Variation (DTV) ≤ 0.010mm and Lateral Runout ≤ 0.050mm
• 100% Mill-Balanced: Electronic mill-balance process ensures smooth, vibration-free braking at all speeds
• Non-Directional Finish: Promotes faster brake pad break-in and smoother, quieter stops
• Ready to Install: No cleaning or degreasing required — saves time and labor during installation
• Plain / Smooth Style: OE-style blank rotor surface for everyday street and commute driving
• 1-Year Warranty: Coverage against manufacturer defects in materials and workmanship

The DFC GeoSpec coated rotor line covers a comprehensive range of foreign and domestic passenger car and light truck applications, making it one of the most complete coated rotor programs available. Each rotor is designed to meet the same form, fit, and function as the OEM part it replaces — no modifications required.
