Take your BMW 4-Series to the next level with the MMX Performance Lowering Spring Set, the ultimate upgrade for drivers who demand precision handling, enhanced aesthetics, and uncompromising ride comfort. Expertly engineered for the F3X platform, these springs lower your vehicle’s center of gravity by up to 40mm in the front and 35mm in the rear, delivering a dramatic improvement in cornering performance and road feel. The result is sharper turn-in, reduced body roll, and a more planted, confidence-inspiring driving experience—all without sacrificing the smooth, refined ride quality BMW is known for.
Crafted with carefully selected progressive spring rates, MMX Springs adapt seamlessly to your driving style: supple and composed during daily commutes, yet firm and responsive when you push the car to its limits. Designed to integrate perfectly with factory static and Adaptive M dampers, this kit preserves suspension travel and maintains OEM balance, avoiding the harshness of overly aggressive setups. Combine this with a strikingly lower stance that visually transforms your 4-Series, and you have a premium performance upgrade that feels as good as it looks.
