It's a sad day indeed, but I DO see your point, and understand your choices.
This makes me VERY reluctant to mod my FiST much beyond where it is now (power train-wise).
The only thing I would even
think of changing out on the Polestar is
maybe the wheels/tires.
I would not even consider a tune, unless it is FULLY warrantied by Volvo, in at least the same way the MP215 is by Ford, and maybe not even then.
Like you said, Ohlins dampers, HUMONGOUS, eyeball popping Brembo brakes, 370 something ponies, EFF IT (the modding that is), drive it like it is and ENJOY IT!!
It was hard to tell from anything I read about it, but is the transmission a true SMG auto, like in the M Bimmers, or is it a very high performance, tight torque converter, many ratio slushbox like the current highly rated GM 10 speed deal?
