Rough ride... Tire Pressure or HAS?
Having a hard time with this one. Appreciate any ideas here on my new M2 G87.
Observation Stiff ride even on "comfort" settings. Almost feel like tires are super over inflated. Setup

I have the factory suspension and find it a little harsher than I’d like at times, particularly on uneven pavement. I am at 36psi but think the comfort pressure is more like 32psi.

I'm not expecting a Cadillac by any means but I do feel every little imperfection on the road which doesn't seem right. I've owned many sports cars in my 25yrs driving and this is a first. Literally feels like I'm driving on 65 PSI tires.

Any chance you still have bump stops on the suspension?

At least when I saw my car in transit mode it was pretty high still. |

If you are driving in temps below 5C (41F) on the stock summer tyres, the tyres will be rough-riding, noisy and lacking grip. They may also vibrate due to flat spots until they have warmed up. A proper winter tyre will solve that.

In that case, it may just be what you perceive as a harsh or stiff ride, unless the HAS changes the suspension tuning significantly over the stock suspension (besides dropping the ride height). I perceive the stock suspension on the G87 as compliant in comfort mode and actually as soft but better controlled than that of our Macan S with standard suspension on 19" wheels. That's with 2.3 bar tyre pressure in all tyres on both vehicles.

I’m feeling you here. No HAS, but it’s just a tad rougher than I remember on the test drive. My tires were set to 40psi from the dealer, so I dropped them down to 33 but it’s not that much better. I wish there was a way to tune the dampers in software to be a little softer in comfort mode.
