Exactly, 8 & 9 is ideal SC/3.2 fitment. You can't fit an 9J under the front of a narrow-body car, 8J is the widest. You can't fit a 10J ET5 under the rear of an SC/3.2 flared car, 9J is the widest. I checked this fact personally a few weeks ago.
It's not even close to being OK without custom sizes, offsets and/or bodywork (extended flares).
8's & 9's bolt straight into flared (but non-widebody) cars and allow the use of quality tires in the cheap, easy-to-find & popular sizes like 225/45 (does require the front fender to be rolled) & 255/40.
(You can probably squeeze in slightly wider tires - especially at the rear, but these are taller/heavier/harder to find/not available in all brands/more expensive. And may also require spring plate bolt heads to be shaved, oil lines relocated, fenders rolled and possibly more aggressive alignment. Diminishing returns... IIRC, 225/255 is wider than Ruf used on the Yellowbird CTR anyway, with 8J/10J and ~470HP - think they spec'd 205/245 back in the day).
