The Eibach Pro-Spacer kit for 2014–2018 BMW 228i is supplied as an 18mm pair of wheel spacers that move the wheel outboard to modify track width. They create additional clearance for wider tires and a broader stance for a more planted look. Offered as a model-specific solution, the kit lets owners adjust wheel position cleanly without changing wheel hardware.
