PRODUCT DESCRIPTION
MMR Performance Lowering Springs for the BMW G20 M340i and 330i (rear-wheel drive and all-wheel drive) offer the perfect combination of improved dynamics and superior aesthetics, without sacrificing ride comfort. The approximately 30mm height reduction at both the front and rear revitalizes the G20, making it feel lighter, with more direct steering and significantly more precise corner entry.
The MMR Performance lowering spring kit is one of our best-selling products. It's no surprise, as it has earned an excellent reputation for delivering the perfect combination of enhanced handling and superior aesthetics, all without sacrificing ride comfort.
Lowering the ride height makes a huge difference to handling characteristics. By lowering the center of gravity of the M340i and 330i, body roll is reduced for better dynamics, while maintaining comfort and ride quality.
Thanks to the careful selection of progressive spring stiffness, ride comfort remains unchanged and is even more pleasant to drive at low speeds. But when accelerating into corners, the G20 chassis comes alive, offering a feeling of lightness, greater precision and a much more agile corner entry. Just what the 3 Series needs.
In addition, the car's aesthetics are transformed. Our development has resulted in springs that reduce the vehicle's height by approximately 30mm at the front, while the rear sits 30mm lower.
If a lower or stiffer suspension than these MMR springs is chosen, the car will bounce and suffer impacts, as the shock absorbers are not correctly adjusted to the spring stiffness and the latter reach their travel limit.
Finished in MMR metallic grey, the sport springs are designed to be fully compatible with vehicles equipped with M adaptive dampers, both static and adaptive. A must-have for any M340i and 330i!
