The MMX Performance Lowering Spring set for the current BMW M135i xDrive F40 models deliver the perfect blend of improved dynamics and enhanced looks, yet without sacrificing ride quality. The 25-20mm drop in ride height brings the car to life, making it feel lighter, more direct and with significantly sharper turn-in.
The MMX Performance Lowering Spring Kit is one of our best-sellers. Little wonder, as they've earned a reputation for delivering the perfect blend of improved handling, enhanced looks, yet all without sacrificing ride quality. The drop in ride-height makes a huge difference to the M135i's handling characteristics: by lowering the vehicle's centre of gravity, it reduces body roll for better dynamics, whilst maintaining the ride quality and comfort of your car.
Thanks to the carefully selected progressive spring rates the ride-quality remains unaffected and is actually nicer to drive at slower speeds. But push-on through the corners and the F40's xDrive chassis really comes to life, making it feel lighter, more direct and with significantly sharper turn-in. Meanwhile, the car's appearance is transformed. The Lowering Springs provide a drop at the front of 25mm whilst the rear sits lower by 20mm. This removes the inherent rake and makes the car sit more level and balanced between the front and rear. By getting rid of those nasty wheelarch gaps, it'll look just how it should have come from the factory!
Go lower or stiffer than these MMX Springs and your car will bounce and crash as the dampers are mismatched to spring-rate, and the springs themselves run out of travel. Finished in MMX Grey, the Sport Springs are developed to be fully compatible with cars fitted with either static or dynamic dampers. A must-fit for your F40 BMW!
