ST Sport Springs for BMW 3 Series F30, F31 and F34 GT — 40 mm Front and Rear Drop

Give your BMW a purposeful stance and sharper road manners with this ST sport spring set. Designed for the F3x platform, these uprated coil springs lower ride height by approximately 40 mm front and rear, improving turn in, reducing body roll and closing that arch gap for a clean, aggressive look. Ideal for daily driving and spirited B-road use, this is the go-to suspension upgrade if you want better handling without sacrificing comfort.
