When you say the 8GC seats are more snug- do you mean less shoulder room or is it tighter bolstering? I have the seat pretty far back in my G30, and the B-pillar kinda limits shoulder room already.

For IAS, look at what's offered on the M cars for the real story. I don't think it's available on the M5 or M8 but it is offered on the 740i(L) which I think says all that's needed to say on IAS.
As for the snug seats, It's mostly bolstering. I'm not a big person so I've never had problems on the 5's with shoulder room. The multi contour seats on BMW's are generally amazing but they lack some of the bolstering.
