ST height-adjustable spring kit for the standard dampers. For the BMW 3 Series (F30, F31, F34).

The ST height-adjustable spring kit replaces your standard springs with ST springs on a threaded sleeve, so ride height can be set smoothly while you keep your original dampers. It suits cars with standard or electronically adaptive dampers where you want adjustable lowering without a full coilover.

How to order

Choose your car from the list. Some cars have more than one version of this kit, to suit strut size, rear axle type and axle weight. We confirm the exact kit against your registration before we send it.

Important: The kit is matched to your original dampers, so worn dampers will limit the result. Set the ride height within the lowering range for your car and have the alignment checked after fitting. Contact us with your registration or VIN if you are not sure which version you need.
