Searching for BMW E46 coilovers, E46 suspension, E46 lowering springs or Bilstein B12? This B12 Pro Kit is the sweet spot for fast-road E46 setups. It offers a measured drop of approximately 10 mm to 30 mm depending on application for a purposeful stance and real-world performance you can feel every mile. If you are comparing BMW E46 coilovers, note that the Bilstein B12 Pro Kit is a fixed-height, matched spring and damper package that often provides better ride quality and long-term reliability than many entry-level coilovers.
