On the ride (and I know it’s an E86) but I have just swapped out my 18” wheels and run flat tyres to 19” wheels with non run flat tyres and the difference is unreal! I don’t think it’s crash at all, form yes but then you would expect that to some degree especially on M Sport suspension. If you like the wheels I would recommend swapping tyres out first.
Looks a lovely car but not sure about the holes in the airbox
