MMX Performance Lowering Spring Kit - BMW G42 230i/M240i RWD

Product Details

MMX Performance Lowering Springs for the BMW G42 230i strike the ideal balance between sharper handling and a more aggressive stance, all without compromising ride comfort. With a drop of approximately 20mm at the front and 15mm at the rear, the G42 gains a more planted feel, offering improved responsiveness, lighter dynamics, and noticeably crisper turn-in.

Lowering the car’s centre of gravity 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 and, in fact, actually feels more composed around town. But push on and the G42’s chassis comes alive: it feels lighter on its feet, more direct, and properly responsive through the corners. Just what the 230i 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, 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.
