Dynamic Friction 4522-63129 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4522-63129 GeoSpec Coated Plain Disc Brake Rotor is a premium OE-replacement brake rotor engineered for reliable, quiet, and smooth stopping performance. Finished in DFC's signature GeoSpec corrosion-resistant coating, this rotor forms a durable, attractive silver-gray finish that provides superior rust protection compared to conventional paint or zinc coatings — and requires no pre-installation cleaning or degreasing.

Key Features:

• GeoSpec Fully Coated Finish — Complete inside-and-out corrosion protection; the coating is safely swept away during normal brake bed-in with no harmful effects on friction surfaces
• Premium G3000/G11H18 Iron Casting — Engineered for superior strength, stability, and long-term durability
• OE Vane Configuration — Duplicates original equipment vane geometry for proper and maximum heat dissipation
• CNC-Machined to Tight Tolerances — Ensures precise fitment and meets or exceeds OE specifications
• 100% Precision Mill-Balanced — Delivers smoother stopping and eliminates vibration at any speed
• Non-Directional Surface Finish — Promotes faster, more even brake pad bed-in for quieter, smoother stops
• Ready to Install — Shipped dry with no additional preparation required, saving time during installation
• Plain / Blank Rotor Style — Smooth rotor surface for OE-style replacement performance

Every DFC GeoSpec rotor passes a 100% inspection station after machining to verify all critical attributes meet OE specifications. Backed by Dynamic Friction Company's limited warranty, the 4522-63129 is a direct-fit replacement rotor sold individually.
