GeoSpec Coating Technology:

• Electrostatic coating process applies a uniform, corrosion-resistant finish to all non-friction surfaces, including the hat, vanes, and edges
• Protects against rust and corrosion during shipping, storage, and everyday driving conditions
• Eliminates the need for additional prep work at installation — ready to mount right out of the box
• Maintains a clean, OE-quality appearance throughout the life of the rotor

Rotor Design & Construction:

• Plain (non-slotted, non-drilled) rotor face for maximum swept area and optimal heat dissipation under normal driving conditions
• Manufactured from high-carbon gray iron for superior vibration damping and fade resistance
• Precision machined to strict dimensional tolerances for proper pad contact and smooth, quiet braking
• Balanced to minimize noise, vibration, and harshness (NVH)
• Direct OE replacement — matches original rotor geometry for a hassle-free fitment
