FYI the 335i has better stopping power than the out going m3.
Bigger calipers also.
And the 335i suspension is a lot more refined than the m3's. Yes the m3's suspension is better for the twisties. But as for cruising when your going 155 mph in a m3 you know your going 155.
Anyone that has owned a m3 and 335i can tell you the 335i's suspension is a lot softer. In my girlfriends old m3 You can feel every fucking bump you went over.
