Bilstein B12 Pro-Kit Suspension Kit 46-180940 for BMW 3 Series E36 (1990-1998) 320i 325i 325td | B8 Dampers & Eibach Pro-Kit Springs | 10-30mm Lowering

Bilstein B12 Pro-Kit Shock and Spring Package 46-180940 for BMW 3 Series E36 320i 325i 325td

Give your E36 the stance, grip and confidence it deserves. The Bilstein B12 Pro-Kit combines Bilstein B8 shortened shock absorbers with Eibach Pro-Kit progressive springs to deliver a tasteful ride height drop, razor-sharp steering response and composed comfort on British roads. Ideal for fast-road use, daily driving and weekend blasts, it is the go-to uprated suspension bundle for drivers who want real-world performance without the fuss of height-adjustable coilovers.

We have fitted this exact setup ourselves and for many MJ Modifications customers, and the feedback is consistently glowing: flatter cornering, reduced dive under braking, less squat on acceleration and a planted, premium feel at motorway speeds. It is the sweet spot between sportiness and refinement for the BMW 3 Series E36 platform.
