The 'is' comes with the standard M suspension. It does not come with the performance springs. The Bilsteins and Eibach sway bars I selected are more aggressive than the BMW performance parts. I had some Eibach pro springs but returned them since I was looking for a subtle lowering. The BMW perf springs lower by 10mm (about 0.4 inches) vs the Eibach pro which lower by 1.2 inches. I'll measure the actual drop from axle to fender before and after the new springs are installed.
