The g80 has different suspension system and chassis, I imagine it can accommodate the lower and stiffer springs with adapting to whatever spring new rate. The 6 series is not an M or sport oriented suspension it’s more for all purpose mostly focus on comfort. The sport mode “stiffens the suspension” but I drive in comfort 99% of the time.

One thing I’ve learned from all my Bimmers is don’t mess with their air flow/intakes, or suspension unless you’re doing a full coilover swap, or dropping 1-2k on a venturi intake.
