Do you notice increased tire wear on the shoulders taking 7 psi out?
You can tell it's a heavy car w/ 40 psi all around factory spec.
Can you give me details on your track experience w/ the car.

I haven't noticed any effect on the longevity of the tires. My current M8 is at 13,500 miles and they're doing just fine.
I haven't taken the M8 to the track. I took both of my M5s to road courses as well as the dragstrip. At the dragstrip, tuned 4WD S63 bimmers are tough to beat especially on racegas with tweaked exhausts. On the road courses--and not too surprising--they're awesome in the straights and competent in the corners but you had better be a loooong way in front of say a Porsche if you still want to be in front when you exit the corner.
If I were to guess, I'd say the M8C Coupe or GC would suffer the same laws-of-physics limitations the M5s suffer from: an object in motion tends to stay in yada yada--they let go at the most inopportune times in the twisties. I will say the M8's carbon core is palpable, though--perhaps it'll help but I don't yet know.
