Dynamic Friction 4812-13113 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4812-13113 GeoSpec Coated Plain Brake Rotor is a premium OE-replacement disc brake rotor engineered for reliable, long-lasting stopping performance. Featuring DFC's proprietary GeoSpec® corrosion-resistant coating, this rotor arrives ready to install straight out of the box — no degreasing or additional preparation required.

The GeoSpec® coating forms a durable, attractive silver-gray finish that provides superior rust and corrosion resistance compared to conventional paint or zinc coatings. The coating is safely swept away by the friction material during bed-in with no harmful effects on braking performance.

Key Features:

• Engineered with premium G3000/G11H18 iron castings for strength, stability, and long-term durability
• Fully coated inside and out with GeoSpec® rust-prevention coating — superior protection over conventional zinc or paint coatings
• OE vane configuration duplicated precisely to ensure proper and maximum heat dissipation
• CNC-machined to the tightest tolerances available for a precise OEM-equivalent fit
• 100% precision cut and mill-balanced for smoother stopping and zero vibration at any speed
• Non-directional brake surface finish promotes faster, more even brake pad bed-in and quieter stops
• Ready to install — processed dry and shipped dry, no pre-installation cleaning needed
• Passes a 100% electronic inspection station measuring all critical attributes to confirm OE specification compliance
• Smooth/plain rotor style — ideal for normal commute, performance street, towing, and light off-road use

The DFC GeoSpec program covers over 1,400 SKUs for a wide range of foreign and domestic passenger cars and light trucks, making it one of the most complete coated rotor programs on the market. Each rotor is designed to meet the same form, fit, and function as the original equipment rotor it replaces.
