Part of DFC's flagship GeoSpec coated rotor program, this rotor features a patented silver-gray rust-prevention coating applied inside and out — fighting rust far better than conventional paint or zinc coatings.

Key Features:

• GeoSpec® Full Coating: Durable silver-gray finish provides superior corrosion protection over conventional zinc or paint coatings
• Premium Iron Castings: Engineered with G3000/G11H18 iron castings for optimal strength, stability, and long-term durability
• OE Vane Configuration: Replicates original equipment vane geometry for proper and maximum heat dissipation
• CNC-Machined Precision: Processed to the tightest tolerances available for smooth, consistent braking
• 100% Mill-Balanced: Every vented rotor is electronically mill-balanced for vibration-free stops at any speed
• Non-Directional Finish: Promotes a faster, more even brake pad bed-in for quieter and smoother stops
• Ready to Install: Shipped dry with no oil coating — no pre-degreasing or additional preparation required
• OEM Form, Fit & Function: Designed as a direct replacement to meet the same specifications as factory brake rotors
• 1-Year Warranty: Backed by Dynamic Friction Company's manufacturer defect warranty

The DFC GeoSpec coated disc brake rotor is an ideal choice for daily commuters and light-truck drivers seeking a premium OE replacement rotor with enhanced corrosion resistance and straightforward installation. The coating is safely swept away by the friction material during break-in with no harmful effects on brake performance.
