Bilstein B12 Pro-Kit 46-264770, BMW F2x sports suspension upgrade for sharper handling and an OEM+ stance

Give your F2x chassis a serious dynamic boost with this Bilstein B12 Pro-Kit. The package combines Bilstein B8 sport shock absorbers with Eibach Pro-Kit progressive rate springs for tighter body control, improved stability and a tasteful ride height drop that looks factory fresh. Ideal for British B-roads and motorway miles, this spring and damper bundle delivers confidence without the harshness often associated with budget coilovers.

We have installed this kit on multiple BMW 1 Series and 2 Series models and customer feedback has been consistently positive. Expect crisp turn-in, reduced roll, better traction out of bends and a composed ride that works brilliantly on UK tarmac.
