Transform your BMW 3 Series ride and stance with ST performance springs
Give your E9x chassis the perfect stance and a sharper, more controlled drive. This ST sport spring set delivers an even 30 mm front and 30 mm rear ride height reduction, improving cornering grip, reducing body roll and dialling in a purposeful look without ruining everyday comfort. It works seamlessly with your standard dampers, including cars equipped with factory electronic damping.
We have installed these springs on customer cars and our own builds, and the feedback is consistently positive: tighter turn-in, more confidence on B-roads and a clean, level drop that looks right on road or track-day. If you are searching for a BMW E90 suspension drop kit, E92 sport springs, E91 Touring coil spring upgrade or an E93 convertible ride height kit for 325d or 330d, this is the one to choose.
