Why enthusiasts choose this kit for the E9x chassis

Dial in the exact ride height you want after installation. No fixed one-size-fits-all drop. Whether you run daily on UK roads or enjoy the odd track day, this height-adjustable spring set helps you achieve the perfect wheel-to-arch fitment and clears different wheel and tyre setups with confidence. It is the smart alternative to a full coilover when you want height control while retaining the character of the stock dampers.
