EBC BSD rear rotors for 2003–2004 Subaru Impreza WRX/STI feature the V‑slot pattern to improve heat dispersion and keep pads cooler than many OE designs. The BSD series emphasizes thermal stability and quieter slot operation, making these vented rear discs suitable for drivers who want both a visual upgrade and improved braking behavior under load. They complement high‑friction pad sets for better sustained stopping.
