E30 Cabriolet B12 Pro Kit - Bilstein B8 Dampers + Eibach Pro-Kit Springs, Part No 46-000156

For E30 Cabriolets that need proper chassis control without turning the ride into a punishment: this is the B12 Pro Kit. Not a generic 'sporty' compromise - it’s the matched Bilstein B8 monotube dampers and Eibach Pro-Kit progressive springs combo enthusiasts specify for fast-road, track-day or daily-driver E30s.

• Bilstein B8 dampers - gas-pressure, monotube, TÜV-approved, built for sustained load and responsive rebound
• Eibach Pro-Kit springs - progressive rate, 10-30 mm drop, tuned to work with B8 valving (not softer Nivomat or stock-spec replacements)
• Direct fit for E30 Cabriolet (all 318i/320i/323i/325i variants, 1982-1993), including convertible-specific geometry
• No guesswork - this is the exact kit referenced in E30 forums as stage 1 chassis upgrade, fast-road E30 suspension, or track-day prep for lightweight E30s
• Part number 46-000156 - matches Bilstein’s official E30 Cabriolet B12 listing
