The MMX Performance Lowering Spring Kit is one of our best-selling upgrades — 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 — by up to 40mm at the front and up to 35mm at the rear (model dependant) — 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 — 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 — 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. Features Sharpened handling with reduced body roll.
