Sport XI springs vs Msport springs, same?

Are the springs the same on an XI Sport as they are on my 335i Msport?

unfortunately not. xDrive springs for all F3x's are soft and mushy like baby food. If you care about handling you probably will be forced to change. Affordable options are currently

-KW v1,v2,v3 coilovers at ~$1,600, ~$2,100, ~$2,500 respectively;
-BC Racing coilovers at ~$1,000;
-Bilstein Sport Struts/Shocks + H&R Sport Springs at ~$1,000;
-Eventually Bilstein PSS10 Coilovers at probably $2,300

I would not change out just springs.

What if I have base suspension? Would it be that big of a deal to swap out for M-sport springs? M-sport and MPS are both 10mm lower, right?
