Dynamic Friction 4522-74007 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) GeoSpec Coated Plain Brake Rotor (Part #4522-74007) delivers premium OE-replacement stopping performance wrapped in industry-leading corrosion protection. Engineered to duplicate original equipment specifications, this plain-style rotor is a direct-fit replacement designed for hassle-free installation.

DFC's GeoSpec coating sets these rotors apart from conventional zinc-plated or painted alternatives. A patented, specially formulated paint forms a durable silver-gray finish that provides superior rust and corrosion resistance — protecting the rotor inside and out, both before and after installation. Unlike some coated rotors, the GeoSpec coating is engineered to avoid contaminating the friction surface, ensuring a clean, proper brake bed-in from day one.

Key Features:

• Full-Coverage GeoSpec Coating — Patented paint coating covers the entire rotor (inside and out) for superior corrosion protection over conventional zinc or standard paint coatings
• Premium G3000 Iron Casting — Manufactured from premium G3000/G11H18 iron casting for superior strength, stability, and long-term durability
• OE Vane Configuration — Engineered to duplicate precise original equipment vane geometry and fitment for a true direct replacement
• CNC-Machined to Tight Tolerances — Precision machining ensures accurate fitment and consistent rotor thickness
• 100% Precision Mill-Balanced — Promotes smooth, vibration-free stopping at all speeds
• Non-Directional Surface Finish — Promotes faster break-in and smoother stops right out of the box
• Ready to Install — No pre-cleaning required; GeoSpec coating protects the rotor until the moment of installation
• Plain (Blank) Style — Solid rotor design suited for everyday street driving and OE-equivalent performance
