Hello Silver,
I've been lowering my 730d about 3 years ago. If I remember right it was
H&R equipment with 25/20mm. I'll proof this in the evening and let you know the details.
In paralell I've upgradet also to 20inch rims.
I couldn't 'feel' any comfort difference before and after but the car looks much more 'sportive'.
I personally wouldn't lower more than what I've done because of the clearance , any heavy hump , especially in parking lots a.s.o can be a problem to get in contact with.

Best regards and have a save day.
