Bilstein B12 Pro-Kit Suspension Kit for BMW 3 Series Touring/Estate/Wagon G21 G81 330d Diesel (incl. 48V Mild Hybrid) - B8 Shocks & Eibach Pro-Kit Lowering Springs - Fast Road Fixed-Height Springs & Dampers - Part No 46-322326

Bilstein B12 Pro Kit - BMW 3 Series Estate G21 G81 330d including 48V Mild Hybrid - Part No. 46-322326

Transform the way your BMW 3 Series Touring drives with a premium spring and damper package that delivers confident handling, real comfort and a purposeful ride height drop. The Bilstein B12 Pro Kit blends uprated B8 dampers with Eibach progressive coils for a fast-road setup that feels factory fresh yet distinctly more focused. Ideal for owners who want the look and performance of a sport chassis without the faff of height-adjustable coilovers.

We have fitted this package on customer cars and the feedback has been consistently positive. Drivers love the flatter cornering, improved stability on B-roads and motorways, and the tidy stance that suits both OEM wheels and larger upgrades.
