Dynamic Friction 4524-31158 GeoSpec Coated Plain Disc Brake Rotor - Rear

The Dynamic Friction Company (DFC) 4524-31158 GeoSpec Coated Brake Rotor is a premium OE-replacement rear disc brake rotor engineered for strength, corrosion resistance, and precise stopping performance. Featuring DFC's signature GeoSpec silver-gray coating, this plain-style rotor delivers superior rust protection and arrives ready to install straight out of the box.

GeoSpec Coating Technology:

• Patented corrosion-resistant coating forms a durable, attractive silver-gray finish
• Fights rust far better than conventional paint or zinc coatings
• Completely coated inside and out for full-surface protection before and after installation
• Coating is safely swept away by friction material during break-in with no harmful effects

Precision Engineering:

• Engineered with premium G3000/G11H18 iron castings for strength, stability, and durability
• CNC-machined to the tightest tolerances for consistent, reliable performance
• 100% precision cut and mill-balanced for smoother stopping and zero vibration at any speed
• Original Equipment (OE) vane configuration ensures proper and maximum heat dissipation
• Non-directional finish promotes faster brake pad bed-in and quieter, smoother stops

Ready to Install:
