GeoSpec Coating Technology:

• Patented corrosion-resistant coating forms a durable silver-gray finish that outperforms conventional paint and zinc coatings
• Processed dry and shipped dry — ready to install with no additional preparation or pre-degreasing required
• Coating is safely swept away by friction material during bedding with no harmful effects

Precision Engineering:

• Cast from premium G3000/G11H18 gray iron for optimal strength, stability, and long-term durability
• 100% precision machined and mill-balanced for smooth, vibration-free stopping at all speeds
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter operation
• Each rotor passes a 100% electronic inspection measuring over 20 attributes to verify OE specifications
• Chamfered and slotted (where applicable) to reduce braking noise

Direct-Fit Replacement:

• Engineered specifically for the application — no modifications required
• Sold as a 2-wheel set (both rear rotors included)
• Compatible with DFC 5000 Advanced, Euro Ceramic, and 3000 Ceramic brake pad lines
