Philadelphia has nothing on the Southeast Michigan area, including Detroit, for crappy roads. Our major political topic is not the presidency, the police, it's how the state will implement legislation for road improvements. Anyway, it's not so much the car...it's very much the wheels and tires.
Here is one solution.

And, a ready finger for the Comfort setting on the MAdaptive suspension switch. I choose Comfort vs. Sport based on two factors:
1) Is my wife in the car
2) What route/road conditions I'm facing
Perhaps DWS06 tires, which as UHPAS, will also be a more forgiving model, while still providing very good performance, although clearly not PSS league. Life is full of trade-offs, but you don't need to trade off the entire car.
