ST Lowering Spring Kit - 20/10 - 4 -series; F32, F33 (3C) Cabriolet / convertible 02/14- 435i

BMW 4 Series F32 F33 435i Performance Coil Spring Set - 20 mm Front / 10 mm Rear Drop

Give your BMW 4 Series the stance and handling it deserves. This ST performance coil spring set is tailored for the F32 Coupe and F33 Cabriolet 435i models from 2014 onwards, delivering a tasteful ride height reduction of 20 mm at the front and 10 mm at the rear. Expect crisper turn-in, reduced body roll and a cleaner wheel arch gap while retaining everyday comfort.

Perfect for drivers who want a factory-plus feel without switching to coilovers, these springs work seamlessly with your original dampers, including cars fitted with electronically controlled shock absorbers such as EDC. We’ve installed this setup on customer 4 Series builds and the feedback has been superb for both looks and real-world performance.
