My dealer explained that the suspension on the coupe is much more sport oriented. He went so far as to say that it is comparable to the outgoing M3.
Watching videos, it looks like body roll is minimal. Can anyone who actually owns a 335iCoupe tell me how the suspension really is for spirited driving (meaning in the curves...anyone can drive fast in a straight line).

Its a nice balance, has less roll than the standard susp. and still keeps enough softness to the ride. As far a being the same as the outgoing M3...not even close really. And not that you would want it to be for this model.

I think it is pretty good, but it's not even comparible to the M3. It need's an LSD to handle the way I would like it too.

Its pretty good, but not the equal of the M3. My E46 performance package was actually a little tighter and quicker than the 335 coupe. I have noticed just a slight amount of body roll as the suspension loads for a curve.
