The other issue is 20inch tires with pzeros, they are rock hard. I'm convinced that this car is built for Germany and not the crap USA roads.
Sorry but I am not going to spend a fortune on changing the whole suspension setup. I'll live with it for now and use the MDX for comfort. The A6 is for fun only.
I have a 13 A6 non sport suspension 3.0T and am going to remove my struts and springs within the next month or two. I would be interested in your sport setup. Let me know if you have any interest. I am in Indiana
