The original shock absorbers are not designed to work well at lowered heights. The shock absorbers will actually wear very quickly and provide a very bad comfort level.

No, the comfort is only slightly affected negatively. In fact, if your car is equipped with an original sport suspension, then your KW suspension will actually be more comfortable (at least for the majority of the applications).

Yes they are. You simply need to set the height within the recommended KW settings. For Belgium, you will need to show your installation document as well as the GOCA validation doc specific to your kit.

We recommend the fully damping adjustable V3 version .If budget does not allow it, we recommend the V1. It does not have any adjustable damping possibilities but is set from factory with a very good handling/comfort compromise.
