This replacement front spring is designed to work on all 323Ci, 325Ci, 328Ci, and 330Ci models. B3 replacement coils are designed to restore your cars handling to the way it was from the factory.
As the springs age, they begin to compress or "sag" allowing the body to sit lower and slightly altering the motion of the suspension. Because of this we strongly recommend replacing these in pairs in order to ensure safe and predictable handling characteristics.
ECS Tuning also offers Bilstein B3 struts and shocks that pair flawlessly with B3 springs and truly restore your vehicles lost handling capabilities.
