Dynamic Friction 9504-63125 GEOMET Coated Plain Disc Brake Rotor Kit

The Dynamic Friction Company 9504-63125 is a GEOMET-coated plain (smooth) disc brake rotor kit engineered to deliver OE-level braking performance with superior corrosion resistance. Part of DFC's 950-series Hi-Carbon Alloy rotor lineup, these rotors are a direct OEM replacement designed to match the original form, fit, and function of factory brake rotors.

Key Features:

• GEOMET® Corrosion Protection: Each rotor receives a full GEOMET® coating — a high-performance, silver-gray finish that outperforms conventional paint and zinc coatings in rust resistance. The coating is processed dry, shipped dry, and ready to install with no additional prep or degreasing required.
• Hi-Carbon Alloy Iron Casting: Engineered with premium G3000/G11H18 iron castings for enhanced strength, stability, noise dampening, and long-term durability.
• OE Vane Configuration: Original Equipment vane geometry ensures proper airflow and maximum heat dissipation for consistent, fade-resistant braking.
• Precision Machined to Tight Tolerances: Disc Thickness Variation (DTV) guaranteed to .010mm maximum; lateral runout guaranteed to .050mm maximum — regularly achieving .007mm DTV and .025mm lateral runout in practice.
• Fine-Turned Finish (1.6 RMS): The precision surface finish promotes improved initial rotor and brake pad break-in for faster, smoother bedding.
• 100% Precision Mill-Balanced: Each rotor is electronically mill-balanced for vibration-free stopping at any speed.
• Plain / Smooth Surface: Non-drilled, non-slotted design ideal for daily driving, towing, and OEM replacement applications.
• 100% Electronically Inspected: Every rotor passes a comprehensive inspection measuring over 20 quality attributes to ensure OE specification compliance.

The GEOMET® finish is safely swept away by the brake friction material during normal use with no harmful effects, making installation straightforward and hassle-free. These rotors are backed by DFC's limited warranty and are suited for passenger cars and light trucks used in normal commuting, performance street driving, and fleet or extreme-duty applications.
