MMX Performance Lowering Springs – BMW G20 M340i / 330i

MMR Performance Lowering Springs – BMW G20 M340i / 330i

The MMR Performance Lowering Spring Kit is one of our most popular upgrades—and for good reason. Known for delivering the perfect combination of sharper handling, enhanced looks, and retained ride comfort, it’s the ideal modification for your G20 M340i or 330i.

Lowering the car’s center of gravity by approximately 30mm front and rear significantly improves driving dynamics. Body roll is reduced, turn-in feels sharper, and the chassis responds more directly, all while maintaining the smooth, comfortable ride you expect from a BMW.

Thanks to carefully selected progressive spring rates, low-speed ride quality remains smooth and even more composed around town. Push through the corners, and the G20 chassis comes alive—lighter, more responsive, and more engaging to drive.

Visually, the lowered stance eliminates unsightly wheel arch gaps, giving your M340i or 330i a factory-correct, aggressive look. MMR Springs are engineered to work in harmony with both static and Adaptive M dampers, ensuring no harshness, bottoming, or crashy ride quality. Available for both RWD and xDrive models.
