Well, if you want to make 100% sure there is no issue with warranty, the only „safe" thing is to get the M Performance Coilovers from BMW itself.
They introduced that with the M2 I think and will slso be available for the new M3/M4. They are basically from KW, but exclusivly manufactured and branded for BMW.
The only thing to keep in mind is that you can lower max 20mm. With KW you can go more, so to the max 40mm that is legal in CH
