The MMX Performance lowering spring kit is one of our top-sellers, and it’s easy to see why. They’re renowned for delivering the perfect combination of sharper handling, enhanced looks, and everyday ride comfort.
Dropping the ride height by 30mm all around makes a noticeable difference to the BMW G20 M340i and M340d’s (RWD) handling. Lowering the centre of gravity reduces body roll, giving more dynamic, precise cornering, while keeping the ride comfortable and controlled.
With carefully tuned progressive spring rates, ride quality remains smooth and even feels more composed at lower speeds. Push the BMW through corners and the chassis comes alive, feeling lighter, more direct, and with markedly sharper turn-in.
On top of that, the car’s stance is completely transformed. The all-round 30mm drop eliminates the factory rake, sits more level, and closes up those unsightly wheelarch gaps, giving your G20 M340i or M340d the aggressive, factory-intended look it should have had from day one.
A front drop of 30mm all around.
Fully compatible with cars fitted with static or adaptive dampers.
Perfect blend of improved dynamics and enhanced looks, yet without sacrificing ride quality.
