BMW 3 Series E90

Maximum performance without compromise

The ST XTA height- and damping-adjustable suspension system represents the flagship of the ST Suspensions coilover range. Featuring motorsport-derived springs, adjustable damping, and aluminium uniball top mounts, it meets the demands of even the most enthusiastic and performance-oriented drivers. With such extensive adjustment options, you can completely transform the character and capabilities of your vehicle in just a few simple steps. Thanks to the use of racing springs, the spring rate can also be tailored to your individual requirements, taking into account factors such as intended use, vehicle weight, and overall setup.

Every ST Suspensions kit is designed and manufactured using state-of-the-art KW Automotive technology. The threaded shock absorber bodies used for ride height adjustment feature a galvanised zinc coating for maximum corrosion resistance. The piston rod of the twin-tube damper is chrome-plated to ensure exceptional durability and long service life. Unlike conventional height-adjustable suspension systems that use anodised aluminium adjustment collars, ST Suspensions employs a newly developed adjustment collar with a stainless-steel core coated in a durable polyamide composite. This design prevents the collar from seizing due to oxidation, allowing the ride height to be adjusted repeatedly even after many years of use.
