Good luck finding 6-lug wheels in anything more than +31mm. Yes, ideally +35mm would be better, but you'll be hard pressed to find any, especially in 18's.
I had no narrow my rear about 2" and I'm running 18x8's with 2wd sheetmetal and 215/40 series tires. My KMC wheels are high offset (+35).
Note, I used to run escalade wheels and they rubbed when I was bagged with the stock axle. I ran 225/45/17's.
I have stock spindles in the front.
