I have a question not sure anyone can answer, although I don't believe it has been answered yet. Hopefully there is someone who can clarify.
My question has to do with the suspension and the chasis dynamics. If you were to compare a 2007 335i with sports package (non Mpackage not available at that time) to a 2011 335is are they essentially the same. Meaning, if you upgraded the exhaust and engine tune would you essentially have the exact same car less the aesthetic upgrades.
Thanks for any insights.
