Designed with precision, these rotors offer consistent stopping power and enhanced heat dissipation for vehicles like the Audi A3 and Volkswagen Golf.

• Cross-drilled solid disc rotor design for improved heat dissipation
• Coated hat finish to resist corrosion and extend rotor life
• Compatible with floating disc mounting for better rotor alignment
• Designed for 5-lug wheel configurations with a 100 mm bolt circle diameter
• Nominal thickness of 9.000 mm and discard thickness of 7.000 mm for durability

Product Specifications and Features

This StopTech rotor features a solid disc construction with cross-drilled surface type to aid in heat management during braking. The rotor has an outside diameter of 230 mm (9.055 inches) and an overall height of 40.5 mm (1.594 inches). The hat section is coated to protect against rust and corrosion, ensuring longevity under various driving conditions. It is designed with a floating disc mounting system, which helps maintain proper rotor alignment and reduces stress on the braking components.

The rotor includes five stud/lug holes with a diameter of 15.75 mm (0.620 inches) and a mounting bolt hole circle diameter of 100 mm (3.937 inches). The center hole diameter measures 65 mm (2.559 inches), fitting securely on compatible hubs. Weighing approximately 6.4 lbs (2.9 kgs), this rotor balances strength and weight for effective braking without unnecessary mass.
