The Eibach Pro‑Spacer 30mm wheel spacer for 2009–2015 Audi A4 (B8) uses a 5x112 bolt pattern and 66.5mm hub centering to ensure proper fit. The 30mm spacer widens the vehicle's track to allow larger tires and deliver a more aggressive stance while improving stability and handling. A wider track helps lower the effective center of gravity and reduce body roll for a more composed driving experience.
