The Eibach PRO-SPACER 20mm wheel spacer for 2003–2008 Nissan 350Z (5x114.3 bolt pattern, 66.1mm hub bore) widens track width to improve stability and handling, increase clearance for larger tires, and create a more aggressive stance. By shifting the wheels outward it helps lower roll tendency and gives a more planted feel while retaining bolt-on simplicity.
