ST 30 mm front and rear coil spring set for BMW 3 Series xDrive E90 E91 E92 325xi 330xi 320xd

Give your BMW 3 Series xDrive the stance and handling it deserves. This ST coil spring upgrade delivers a balanced 30 mm drop front and rear for a cleaner wheel arch gap, sharper turn in and a more planted feel on British roads. Designed to work seamlessly with your factory dampers, including cars fitted with adaptive damping, it is a proven, road-friendly way to enhance grip, reduce body movement and refine the look of your E90, E91 or E92.

We use this kit on our own builds and customer cars with outstanding results. Owners love the improved stability, the confident cornering and the tasteful, even ride-height reduction that keeps daily comfort intact.
