The EBC BSD sport front rotor set for 2017+ Audi A4 2.0L Turbo (B9) uses a V-slot pattern to improve heat dispersion and keep pads cooler compared with OE-style discs. These vented front rotors measure 314mm diameter and 25mm thickness with a 68mm center hole and five bolt holes. High-carbon, thermally stable construction and a silent V-slot layout add durability and refined braking.
