Hi Mate, Simmons are 22x8.5 and 22x9.5 on the rear. The thing about these wheels is they are MADE for this car in reality. The fit so much better than my old Chip Foose wheels which I had machined and all sorts of stuff but in the end it was hard to get real low.
My rear guards were cut and rolled when I first bought the car back in 2012 and whilst its near impossible to not get tiny ripples in the arch with the VE, my ones are pretty good. Saying all that the VE sedan def has less room than the ute, but there is another Russo car, a white VE SS sedan with plates MISSV8 that is really low and I know it doesn't scrape with 5 people in the car so you should be fine.
