MMX Lowering Springs for BMW 4 Series Coupe (F32) RWD
The MMX Performance Lowering Spring Kit is one of MMX’s best-selling upgrades, and it’s easy to see why. Renowned for delivering the perfect blend of sharper handling, an improved stance, and everyday comfort, it is the ideal first modification for the BMW F32 4 Series Coupe.
Lowering the car’s centre of gravity makes a real difference in the way it drives. Body roll is noticeably reduced, turn-in feels sharper, and overall dynamics are greatly improved, all while retaining the comfort and refinement expected from a BMW.
Thanks to carefully chosen progressive spring rates, low-speed ride quality remains smooth; in fact, it actually feels more composed around town. But when the car is pushed, the 4-Series chassis truly comes alive. It feels lighter on its feet, more direct, and properly responsive through corners, just what the 4-Series needed.
Visually, the difference is just as striking. The lower ride height gives the car a more aggressive, purposeful stance without being over-the-top.
Going any lower or firmer than these springs risks upsetting the balance, with mismatched damping and limited spring travel leading to a crashy, unsettled ride. This is why MMX Springs are engineered specifically to work in harmony with both static and Adaptive M dampers.
It is important to note that vehicles equipped with factory-installed M Sport suspension are already lowered by approximately 10mm from the standard ride height.
