If you lower the car too much with MP coils you will hit the wheel with the spring because of its wider diameter compared to KW spring.

But do you really need to lower the car more than 25 mm?

MPerf coilovers have progressive rate front springs (varying, larger diameter) whereas KW v3 have linear rate spring (constant diameter) with intermediate perch and an assister spring.
Rears - KW v3 uses shorter springs than oem coilovers.
Retrofitting KWv3 springs F&R is doable if wanting to switch towards v3 spec on oem coilovers.
Agree wrt to yr comment about lowering more than 25mm - here's my m2 on MPerf coilovers - its low enough.
