From my understanding the biggest weakness of the stock suspension is the rebound, the ZCP doesn't change that. The button still only deals with the compression element.

I would agree that standard EDC suspension in sport setting is a mess, I never use it. Normal is perfect for fast road driving, supple and deals well with bumps. It's not great at very fast transitions but that is not helped by the cars weight. The drop would be nice cosmetically, but you could just get DINAN stage 1 and have basically the same effect.

Recently I have ridden in a number of non performance cars that felt a lot choppier and no where near as well dampened. I rode in a Mazda 6 with 30k miles on it and it felt awful, same with and f10 5 series I rode in which felt very over sprung (this affects a lot of modern cars looking to be 'sporty') despite having huge sidewall tires.


Ultimately the stock M3 suspension is fantastic, compromised if you want more extreme but for a huge spectrum of driving types its very impressive. Every time I cruise in comfort mode i'm reminded at just how civil it is when you want it to be.
Good post. I agree on the suspension overall - extremely good for an out of the box solution at my age (42). I do agree that it doesn't do well over sharp/quick ripples or transitions but really, there's always a compromise.

An Ohlins RT, for example, is really good over the sharp/quick transitions but much too 'firm' for normal driving. Can't have your cake with suspensions, I'm afraid (and I've used a lot of different setups).

Interesting note about the steering response with 359s... is the only variable the wheels (meaning identical tires/sizes)?
