Coilover kits combine shock absorbers with a coiled suspension spring. Because they’re fitted together, they give you more control over dampening and ride height than regular suspension. This is why they are a very popular upgrade, and also why there are so many kits on the market. They come in all shapes and sizes, including top brands like Apex. There are BMW coilovers that are ideally suited for your BMW Z4 (E89), and will be easy to fit too. If you’re looking to drop your ride height or just feel it’s time for a new suspension system, then talk to us at LK Performance about how best to do it. Our experts are always on hand to discuss your options and we just love to talk about BMW coilover kits.
