GeoSpec Coating Technology:

• Fully coated inside and out with a patented rust-prevention paint, forming a durable and attractive silver-gray finish that outperforms conventional paint and zinc coatings
• Coating is designed not to contaminate friction or rotor surfaces, ensuring proper brake pad bed-in and consistent wear characteristics
• The coating is safely swept away by the friction material during normal break-in with no harmful effects

Premium Construction:

• Engineered with premium G3000 iron castings that duplicate precise OEM vane configurations for maximum heat dissipation and an exact OE fit
• CNC-machined to the tightest tolerances available in the market for consistent performance
• Non-directional surface finish promotes faster, more even brake pad bed-in for quieter and smoother stops
• 100% precision mill-balanced for vibration-free braking at any speed
• All vented rotors are 100% inspected for balance and electronically corrected if necessary

Ready to Install:
