MMX Performance Lowering Springs?for the BMW?435i, 440i, 430d, and 435d??a in both?RWD and xDrive?variants ?a deliver the perfect blend of enhanced handling and a more aggressive stance, all while preserving everyday ride comfort. Lowering the front by up to 40mm?and the rear by up to?35mm, these springs give your 4-Series a more planted feel, with improved responsiveness, reduced body roll, and sharper turn-in characteristics.

The perfect blend of improved dynamics and enhanced looks, yet without sacrificing ride quality.

The MMX Performance Lowering Spring Kit is one of our best-selling upgrades ?a and it?¡¥s easy to see why. Renowned for delivering the perfect blend of sharper handling, improved stance, and everyday comfort, it?¡¥s the ideal first mod for your BMW F32 and F36 4-Series.

Lowering the car?¡¥s centre of gravity ?a by up to 40mm at the front and up to 35mm at the rear (model dependant) ?a makes a real difference to 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 you?¡¥d expect from a BMW.

Thanks to carefully chosen progressive spring rates, low-speed ride quality remains smooth ?a in fact, it actually feels more composed around town. But push on, and the 4-Series chassis really comes alive: it feels lighter on its feet, more direct, and properly responsive through the 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.

Go any lower or firmer than these, and you risk upsetting the balance ?a with mismatched damping and limited spring travel leading to a crashy, unsettled ride. That?¡¥s why MMX Springs are engineered specifically to work in harmony with both static and Adaptive M dampers.

Vehicles equipped with factory-installed M Sport suspension are already lowered by approximately 10mm from the standard ride height.
