LK Performance have extensive experience in the vehicle performance sector which allows us to provide you with one of the most comprehensive ranges of BMW, Z4 (E86) suspension kits for a whole range of makes and model of car. Air suspension was first introduced in the middle of the 1990s with a two way system which controlled the inflation and deflation of the suspension. Since then, as technology has evolved the components have been refined further to provide a much smoother drive. The BMW air suspension facilities now enable you to effortlessly control it from the inside of your car, amending the suspension to meet the differing road types. As well as our quality products, the customer service of LK Performance is second to none and we have a dedicated customer support team who can answer any questions that you have, direct you to the right products and offer guidance on delivery and other common questions. The air suspensions that we provide are the best that you can find and the most affordable too!
