The Dynamic Friction Company 4504-31130 is a GeoSpec Coated plain (smooth) disc brake rotor kit, engineered as a direct OEM replacement for passenger cars and light trucks. DFC's GeoSpec coating forms a durable, attractive silver-gray finish that provides superior corrosion protection compared to conventional paint or standard zinc coatings, so rotors arrive ready to install with no additional preparation required.

Each rotor in this kit is cast from premium G3000/G11H18 iron for exceptional strength, stability, and long-term durability. CNC machining to the tightest market tolerances and a non-directional surface finish promote faster, more even brake pad bed-in for quieter and smoother stops right from the start. All vented rotors are 100% electronically mill-balanced to eliminate vibration at any speed.
