Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is constructed as a solid rotor with a slotted and drilled surface pattern to improve brake pad bite and aid in heat and gas dissipation during braking. The rotor’s plain disc finish combined with a zinc silver hat finish provides corrosion resistance, further enhanced by a rust-resistant coating to extend rotor life. The rotor measures 282 mm in outside diameter and 48.5 mm in height, fitting vehicles with a 5-lug bolt pattern spaced at 112.1 mm. The nominal thickness is 12 mm, with a discard thickness of 10 mm, ensuring clear service limits for maintenance.

Compatible Vehicles and Applications

This brake rotor is compatible with a range of Audi and Volkswagen models, including the Audi A3, A3 Quattro, Q3, Q3 Quattro, and Volkswagen Bora, CC, Eos, GTI, Jetta, Jetta City, Passat, Passat CC, Tiguan, and Tiguan Limited. It is designed to meet the braking demands of these vehicles, providing consistent performance for daily driving and moderate performance needs.

Common Issues Addressed by This Rotor

• Brake fade caused by overheating during extended braking
• Uneven brake pad wear due to rotor surface imperfections
• Corrosion and rust buildup on rotor surfaces
• Vibration or pulsation during braking from warped rotors
• Reduced braking efficiency from glazed or contaminated rotors
