The drag of 1M is really an issue (petit but yes an issue) at speeds over 200 km/h or so, which lets for example an M3 or a Cayman etc. starts walking away after some point. The front actually creates down force but as you pointed out the rear has quite a lift which you can tell if you reach high speeds, it is not as planted as a E9X car, period. My old E90 330i was more stable after 200 km/h than my 1M. If you don't want a Moto GP type of wing (I don't
) which may be the only real cure, than a combination of performance spoiler plus Revezport difuser and its undertray (ground effect panel they say) may help to stabilize the rear better. But there are no numerical data that I am aware of regarding both products.
