Bilstein BMW M3 G80 B1 Module - Active to Passive Suspension Conversion Kit

If you want to replace the M3's factory electronic dampers with conventional passive shocks, the car will normally complain about the missing hardware. Bilstein's B1 conversion kit fixes that. It plugs into the factory wiring and keeps the warning lights off once the electronic dampers are gone.

What you get

• Plug-and-play connection to the factory damper harness.
• No dash warnings after the electronic dampers come out.
• A kit built for this specific car, with every component it needs.
• Instructions included in the box.
