The Bilstein B12 Pro-Kit is a complete bolt-in suspension system that pairs Bilstein B8 Performance Plus dampers with progressive-rate Eibach Pro-Kit lowering springs, matched and tuned for the Audi A5 Quattro and S5 (2008-2017). It lowers the front roughly 25mm and the rear roughly 20mm for a balanced stance and improved handling while retaining a comfortable, factory-quality ride.
