We did a 70 with the following
18 x 10 with 5.5 bs running a 315 up front (trimming of the outer wheel lip is required
18 x 11 with 6.5 bs and a 315 in the rear.

My wheels are larger and taller than anyone has mentioned on here and I don't have any issue with clearance, etc. I'm running a 20x9 up front and it turns normal without any rubbing whatsoever. I think you would have been safe with the 9" wheel.

Agreed. Front control arms play a huge role here. With stock arms, forget it. I had CPP on the front of my car that limited how much backspace I could run. They were similar to stock arms, but not as restrictive. With my new Global West front arms, I have no restrictions with back spacing. I have an 8" front wheel, but I can FOR SURE go in another 1.5", and still not hit frame, sway bar, etc.

That's good to know, I'm building a 71 Chevelle and I'm running UMI upper and lower control arms, I was wondering if I could have run a wheel with less backspacing than the stock arms would allow.

I'm also at a point of needing a tire/wheel setup for my '69 Chevelle.
I run the Speedtech ATS front forged spindle and GW tubular upper/lower control arms.
I would love to run a 315/30/18 at all corners.... 
Aside from trimming the front fenders were there any mods to the rear? ie frame rail or 1/4 panel lip mod?

Didn't Scott Mock do this on his Chevelle? Perhaps I'm thinking of another car?
