Detailed Product Description
The StopTech Sport Cross-Drilled Disc Brake Rotors are designed specifically for the Audi S4, ensuring compatibility and optimal performance. Featuring a vented rotor construction with straight vane style, these rotors promote efficient airflow to reduce heat buildup during braking. The cross-drilled surface pattern enhances water and gas evacuation, improving brake pad contact and reducing fade. The coated hat finish protects against rust and corrosion, maintaining rotor integrity over time. With a floating disc mounting system, the rotor allows slight movement to accommodate thermal expansion and reduce stress on the braking components. The rotor measures 345 mm in outside diameter with a nominal thickness of 30 mm, meeting the precise specifications required for the Audi S4 brake assembly.
