Hello all. I have a 2019 M Sport+ 440i. I am looking for suggestions to upgrade the suspension. I do not want it lower or stiffer. I am looking for more control, predictability and less harshness. At under 20k miles, there are no faults with the factory suspension, I believe it could be better. I don't drive the car hard, its more like fast touring.
I am aware of the Bilstein system that Birds BMW have developed, does anyone have experience of this system? Any alternative suggestions would be appreciated.
