MMX Performance Lowering Spring Set - BMW F40 M135i xDrive

The F40 M135i xDrive is quick, but it sits like a family hatch with too much gap over the tires. The MMX Performance Lowering Spring Set drops it 25mm up front and 20mm at the rear, closing the arches and sharpening turn-in without wrecking the ride you rely on every day.

They are tuned to work with the OE dampers, static or adaptive, so there is no need to change anything else.
