Product Description

These MMX lowering springs are designed specifically for the BMW F40 M135i xDrive. The kit replaces the original springs to lower ride height while retaining the factory suspension damper arrangement.

MMX quotes approximately 25mm of lowering at the front and 20mm at the rear. The springs are intended for cars with compatible conventional or adaptive factory dampers; final height varies with vehicle specification.

FAQs

What does the MMX Performance Lowering Spring Kit do?

It lowers the car, improves stance, reduces body roll and sharpens handling response while retaining everyday ride quality.

Which vehicle does this kit fit?

It is designed for the BMW F40 M135i.

How much does the kit lower the car?

The supplied information contains conflicting figures. The main description states 25mm front and 20mm rear, while the feature list states 20mm front and 30mm rear. This should be confirmed before ordering or publishing.

Will it improve handling?

Yes. By lowering the centre of gravity and using carefully optimised progressive spring rates, the kit helps improve cornering dynamics, turn-in and chassis response.

Will it make the ride too harsh?

The springs are designed to improve handling without sacrificing ride quality. The progressive rates help retain comfort during everyday driving.

Does it work with Adaptive M dampers?

Yes. The supplied information states the springs are compatible with Adaptive M dynamic dampers.

Does it work with static factory dampers?

Yes. The kit is designed to work with static factory dampers as well as Adaptive M dynamic dampers.

Why not go lower or stiffer?

Going too low or too stiff can cause the car to bounce or crash over bumps if the dampers are mismatched to the spring rate or the springs run out of travel.

What colour are the springs?

They are finished in MMX Metallic Gunmetal Grey.

Are dampers included?

No. Dampers are not included unless supplied separately.

Is alignment required after fitting?

Yes. A full alignment is recommended after fitting lowering springs.

What should I check before ordering?

Please confirm exact vehicle model, year, drivetrain, damper type, suspension setup and the correct lowering amount before ordering.
