ST Sport Lowering Springs – BMW 340i / 440i (F30/F32, RWD) B58

OVERVIEW

ST Sport lowering springs drop the F-chassis B58 340i and 440i (RWD) for a sportier stance and lower center of gravity while retaining the factory dampers. Made from chrome silicon steel in a cold winding process and multi-coated with a final epoxy layer, they deliver OEM-level quality and finish while standing up to all weather conditions without corrosion or rust.

ST is a sister company of KW and engineers to the same standards — spring rates are matched specifically to your OEM shocks so the driving dynamics are improved without compromising safety or ride quality.
