The MMX Performance F31 3-Series Touring Lowering Spring Set delivers the ideal balance of sharper handling and a more aggressive stance, without compromising the everyday ride quality that makes the F31 such a versatile platform. Whether you're running a 330i, 335i, 340i, 325D, 330D, or 335D (in RWD or xDrive) this spring set tightens up the chassis and gives the wagon the planted, tucked-in look it deserves.
Engineered specifically for the F31 Touring's weight distribution and rear suspension geometry, these progressive-rate springs drop the front by approximately 30mm and the rear by up to 25mm, with the xDrive variant tuned for the additional front-axle weight of the all-wheel-drive system. The result is reduced body roll, crisper turn-in, and a more responsive front end through the corners.
Daily driving manners stay intact. The ride remains compliant over road imperfections, and the spring rates are tuned to work with the OE damper, so there's no need to throw away your factory shocks the day you install them.
The perfect blend of improved dynamics and enhanced looks, without the harshness or compromise of a coilover setup.
