Having been out in the SPC project IS the standard chassis setup handles the 330bhp very well even at high speed - so going charger first everything else later is not ever going to be a problem.
I know the brakes are rated well above what the 1st gen IS puts out and its mostly the body roll that most people have problems with handling wise - hence the many recommendations you have got/will get for uprated ARBs.
