GeoSpec® Coating Technology:

• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and durability
• CNC-machined to the tightest tolerances available
• 100% precision cut and mill-balanced for smooth, vibration-free stopping at any speed
• Non-directional finish promotes faster, more even brake pad bed-in for quieter and smoother stops
