Product Description


To fit E9x 3 Series M3 + Non M3 models

For those people that want to run proper coilover suspension with the ability to lift the nose of the car over obstacles; The future is here!

The E9x kits use a unique damper design for the HSD so requires a separate washer style. A rear option is not available for this kit due to the inboard rear spring.

The kit sits between the main spring and the spring top cup on the coilover and is just 20mm when not inflated. At full extension the cups measure approximately 70mm, so provide approximately 50mm of lift. 
Stiff spring rates can reduce how much the kit lifts, and helper springs or spring droop are sometimes recommended when fitting these cups, so they are not fighting the main spring rate too much in addition to the weight of the car.


The air cup is mounted on the top of the spring and just act like a spacer. When you put pressure on system, the air cup will expand and the car will raise with 50mm. The air cup lift system does not affect the ride quality and performance of your coilovers.
