BMW 1 Series E81 E87 Handling Upgrade - Bilstein B12 Sportline 46-180506 Spring and Damper Package

Transform the way your BMW 1 Series turns, grips and looks with the Bilstein B12 Sportline kit, part number 46-180506. This complete shocks and springs package pairs Bilstein gas-pressure performance dampers with sport springs to deliver a lower centre of gravity, crisp steering feel and confident high-speed stability. Expect an assertive drop of up to 50 mm, a purposeful stance and real-world ride quality that works on British roads.

Ideal for spirited road use and daily driving, this set ride-height solution is engineered specifically for the E81 and E87 platform, covering 116i, 118i and 120i petrol models. It is a direct replacement for tired factory suspension, giving you the precision of an uprated chassis without the complexity of height adjustment.
