GeoSpec® Coating Technology:

• Specially formulated patented coating forms a durable, attractive silver-gray finish that fights rust and corrosion far better than conventional paint or zinc coatings

• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and long-term durability
• CNC-machined to the tightest tolerances available for precise fitment and consistent performance
• OE vane configuration ensures proper and maximum heat dissipation
• Non-directional surface finish promotes faster, more even brake pad bed-in for quieter and smoother stops
• 100% precision cut and mill-balanced for vibration-free stopping at any speed
• All vented rotors are 100% inspected for balance and corrected using a state-of-the-art electronic mill-balance process

OE Specifications & Fitment:

• Designed to meet the same form, fit, and function as OEM brake rotors
• Passes a 100% inspection station measuring all critical attributes to ensure full OE compliance
• Plain/smooth rotor surface — ideal for OE replacement, everyday commuting, performance street use, towing, and off-road applications
