You are correct, when it comes to handling, the OEM runflats perform better than the Michelins. But increasing your tire pressure will NOT improve handling. It will change the feel making the cornering "feel" crisper, but traction will be less leading to slightly increased chance of under/over steer. Increased pressures over recommended will also wear the centers of your tires quicker.
When most people run their street cars with street tires on the track, they decrese the tire pressure from recommended. For instance, I decrease mine 3 PSI on my M3.
The only time you should stray from the OEM recommend pressures is when you change tire size. Here the general rule of thumb is larger tires require less PSI.
