Lowering springs are an affordable way to lower your car and reduce body roll while keeping the factory dampers. Coilovers replace the springs and dampers together, letting you adjust ride height and usually damping – ideal if you want to fine-tune the car or use it on track.

It depends on the product. Lowering springs give a fixed drop, listed on each product page, while coilovers have an adjustable height range. A lower car needs more care on ramps and speed bumps.

Many lowering springs are designed to work with factory adaptive (electronic) dampers, but not all. Each product page lists compatibility – if your M140i (F20/F21) has adaptive suspension, check before ordering or ask our team.

Yes. Changing ride height alters the suspension geometry, so a full four-wheel alignment is needed after fitting to protect your tyres and keep the handling right.
