I have a 2005 E90 330d with sport suspension. I am considering changing the suspension to the SE parts for comfort. Would SE shocks and springs just swap in or would I also need to change other components such as the anti roll bars?

Shocks and springs will bolt in between all xi or non-xi cars (not interchangeable), but be careful of spring rates regarding different models/weights, and find the components from a similar spec car other than suspension.

Anti roll bars contribute to the suspension feel and are different, but do not need to be swapped if you don’t want to.

Thanks for the response! Shocks and springs sounds like a doable project.

Forgive my ignorance but what does "XI" mean?

An XI car is an AWD car. They sit higher than the SE suspension.
