Bilstein B12 Pro-Kit 46-000132 Shocks & Springs Kit for BMW E30 3 Series Convertible/Cabriolet 320i 325i (82-93) – B8 Dampers + Eibach Pro-Kit Lowering Springs – 51mm Front Strut – 10–30mm Drop Sport Suspension Kit

Sport Spring and Damper Package for BMW E30 Cabriolet 320i and 325i - Part No. 46-000132

Give your classic 3 Series Convertible the road presence and control it deserves with this premium spring and shock absorber bundle, part number 46-000132 (also listed as BILSTEIN-46-000132). This fast-road setup combines B8 performance shock absorbers with Eibach Pro-Kit progressive coils to deliver crisp turn-in, reduced body movement and a lower, purposeful stance while keeping everyday comfort intact.

Ideal if you want a BMW E30 cabrio sport suspension upgrade without going to height-adjustable units. It is a superb spring and damper kit for drivers who value stability, steering feel and OEM-grade reliability on British roads.

Why it works on an E30 Convertible

• Matched components - sport shocks are tuned specifically for the included Pro-Kit progressive springs for balance and control.
• Ride height reduction of around 10 to 30 mm depending on vehicle spec for a confident, even stance.
• Sharper response, extra cornering grip and better high speed stability with less roll and pitch.
• Monotube gas pressure technology for consistent damping even on B-roads and during spirited drives.
• Progressive-rate coils give compliance over rough tarmac yet tighten up when pushed.
• Engineered in Germany with Über-high quality standards and longevity you can trust.

We have installed this setup on customer E30s and on our own cars. Feedback from owners is that the ride feels planted without being harsh, the stance is spot on and confidence at speed noticeably improves.
