Bilstein B12 Pro-Kit Suspension Kit 46-281784 for BMW F30 F32 F80 F82 (3 & 4 Series incl. M3/M4) B8 Dampers + Eibach Pro-Kit Springs, 1030mm Lowering

Bilstein B12 Sport Suspension Set for BMW F30 F32 F80 F82 including M3 and M4 - Part No. 46-281784

Give your BMW 3 Series or 4 Series a serious handling boost with a matched shocks and springs package that is built for fast road use and everyday comfort. This fixed-height system combines Bilstein B8 short-stroke gas dampers with Eibach progressive sport springs to deliver confident cornering, a lower centre of gravity and a purposeful stance without the faff of adjustable coilovers.

Perfect for F30 and F32 owners as well as F80 M3 and F82 M4 drivers who want sharper response, reduced body movement and premium ride control on UK roads. We run this setup ourselves and have installed it for many customers. Feedback is consistently positive for grip, stability and the tidy, level drop.
