Dynamic Friction 4002-63144 GeoSpec Coated Cross-Drilled Disc Brake Rotor

The Dynamic Friction Company 4002-63144 GeoSpec Coated Drilled Brake Rotor is a direct OE-replacement disc brake rotor engineered for drivers who want enhanced corrosion resistance and improved braking performance. Featuring DFC's proprietary GeoSpec® coating technology, this cross-drilled rotor delivers a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings.

GeoSpec® Coating Technology:

• Superior corrosion protection — outperforms conventional paint and zinc-based coatings
• Forms a durable, attractive silver-gray finish over the entire rotor including the hat
• Processed dry and shipped ready to install — no degreasing or additional prep required
• Coating is safely swept away by friction material during break-in with no harmful effects

Premium Construction & Precision Machining:

• Engineered with premium G3000/G11H18 iron castings for strength, stability, and long-term durability
• CNC-machined to the tightest tolerances available in the market
• OE vane configuration ensures proper and maximum heat dissipation
• 100% precision cut and mill-balanced for smooth, vibration-free stopping at any speed
• Non-directional surface finish promotes faster brake pad bed-in and quieter, smoother stops
• Cross-drilled holes enhance cooling, improve wet-weather bite, and help expel brake dust and gas

Direct OE Replacement:

• Designed to meet the same form, fit, and function as the original equipment rotor
• 100% inspected for quality assurance before shipping
• Ready to install straight out of the box — saves time and money on installation

The Dynamic Friction 4002-63144 is the ideal choice for drivers seeking an OE-quality replacement rotor with added corrosion protection and the performance benefits of a cross-drilled surface design.
