To be absolutely honest here, for someone as experienced as yourself, who is not happy with the setup, I'm surprised you haven't made a fundamental 'first move' and get 4 tyres on the car which are the same. BMW chassis do not work as well with mixed tyres, proven so many times, with many models, by many experienced drivers. Two run-flat and two non run-flat are asking for strange handling characteristics. If it was me, I'd try a "set" of tyres before changing over to the new suspension and setting it up. Until you have a true benchmark of what the car will be like on the tyre of your choice, (as a set), you have likely compromised and/or strange handling anyway. I'd eliminate one variable before the new suspension, get some 'butt' data.
Not at all surprised you are not happy with some of its characteristics at present, with mixed tyres.
