MP Springs (for my car):
31 33 6 860 630
33 53 6 860 619

Interestingly for M240i's I found that ETK showed that only the front springs are to be changed for M Performance springs option (SZP5A).

European RHD, 2WD:

M135i std Springs: 31 33 6 851 921 & 33 53 6 851 928 MP: 31 33 6 860 629 & 33 53 6 860 619 (Passive only)
M235i std Springs: 31 33 6 865 634 & 33 53 6 865 637 MP: 31 33 6 860 630 & 33 53 6 860 619
M240i std Springs: 31 33 6 865 635 & 33 53 6 865 637 MP: 31 33 6 860 630 (Front only!) 31 33 6 860 631 if ZP Auto
M140i std Springs: 31 33 6 865 634 & 33 53 6 865 638 MP: 31 33 6 860 630 & 33 53 6 860 620

Apologies for being off topic
I just called dealer. They told me I already have the M perf adaptive suspension. There's nothing firmer straight from the BMW factory. I'll have to go aftermarket.
