Z4 M Springs on Z4 Non-M
Does anyone know if the springs are interchangeable? I did search but didn't see this, guessing because it either doesn't fit or no one has tried. Obviously the stock Z4 non M shocks won't be valved for the Z4 M springs, but it does seem that the Z4 M springs are taller than Z4 non M w/ M sport suspension. Looking for a setup that isn't lower than Z4 non M w/ M sport with a stiffer spring rate. Most coilovers seem to be set up to drop.
