Detailed Product Description

The StopTech Sport Cryo-Treated Cross-Drilled Disc Brake Rotors are designed to meet the specific braking requirements of Audi A4, A4 Quattro, A6, A6 Quattro, A8, and A8 Quattro vehicles. Featuring a vented rotor design with straight vanes, these rotors promote efficient heat dissipation to reduce brake fade during extended use. The cross-drilled surface enhances water and gas evacuation, improving wet weather braking performance and pedal feel.

The rotors undergo a cryogenic treatment process that stabilizes the metal structure, increasing rotor life and resistance to cracking. The coated vented hat finish provides additional protection against corrosion, maintaining rotor integrity over time. The floating disc mounting system allows for slight rotor movement, which helps reduce stress and improves overall braking consistency.
