I'm in the market for new wheels, likely going custom.

I can't decide if an 18x11 setup will fit without any major challenges. I would likely go with an r888 315 rear tire.

Preferably I'd not have to roll the fenders.

Stock coils, Cut Springs 1/2", 3/4" drop respectively. In my new setup, I would ditch my 1" spacers in the rear, otherwise the suspension is stock. Car is wrapped for storage ATM, but if I recall, the IRS bolt is shaved; no button head.

Thoughts on 18x11 with a (+20-22) 6.75ish or (+27) 7ish" backspacing?

or should i play it safe and go with a 18x10.5 setup?

Up front I'll go with a 18x9.5 +20ish for a 6.25 backspacing.

Does anyone have any suggestions or experience?

Thank you in advance for the help,
Kenny

I don’t know the numbers but plenty of us run 11s with no problems but you probably will need to roll being lowered.

I use 11x17 with 5.5 back space. rolled lip just for extra safety. You could up to 6.75 and have clearance in and out. I use 28 tall so I had to stay out of the inner wheel well.

I’m running 18x11s with a 315/30 and 3/8” spacer in rear for added clearance but even without no fitment issues at all. And I’m lowered on H&R race springs
