Currently have 2019 M5C, my second M5, previously had F10 which was also an amazing all round car.
Issue I have is that I am finding the competition suspension is a little to firm & choppy for the terrible roads here in the North of Scotland.
What would be the recommendation solution to soften the ride, I am OK if it means slightly increasing the ride hight as that would be an acceptable payoff for a softer ride.
Look forward to your recommendations and ideas.
Thank you.

If you have steel brakes, 19” wheels use tires with more sidewall and that improved the ride. Using comfort inflation pressure rather than stock also helps. Changing to base springs is a lot of work but wound also help.

Thank you for the quick response.
Yes steel brakes with 20" wheels currently on the car.
Not sure about going smaller on the wheels I do prefer the 20" larger wheels.
Tyre pressure currently at recommend pressure, how much lower PSI should I go?
I ldo like the sound of the base springs, does anyone know the part number for these and how much would this increase the ride height?
