Bilstein 46-000101 B12 Package for BMW E30 3 Series 320i 323i 325i 325e 2.7

Give your classic 3 Series the road manners it deserves with the Bilstein B12 package, part number BILSTEIN-46-000101. This matched spring and damper set pairs Bilstein B8 uprated shock absorbers with Eibach Pro springs for a direct-fit upgrade that sharpens handling, reduces roll and delivers a purposeful ride height without ruining comfort. It is a brilliant fast-road solution for drivers who want precision and control on British B roads with day-to-day usability.

We have installed this package on customer E30s and on our own builds. Owners consistently report crisper steering response, better grip in poor weather and a planted, confidence-inspiring feel at speed. If you are chasing a quality E30 chassis refresh that avoids the harshness of budget coilovers, this kit is the sweet spot.
