The Eibach Pro‑Spacer 20mm wheel spacer for 2006–2011 Honda Civic Si provides a vehicle‑specific 5x114.3 bolt pattern and 64mm hub centering to fit correctly. Pro‑Spacer kits widen the track to increase clearance for larger tires and give a more aggressive stance while improving stability and handling by lowering effective center of gravity and helping reduce body roll for cleaner on‑ and off‑road capability.
