16x8 = yes so far

A few responses

Its stock a body rear converted to LBP

went 16x8 to have square wheels for now and have option to go 245 in the rear

5in back space clears in the front but may rub sway bar on hard cornering (ffi sway bar)

I'll check to see on the 16x7 for the front its a good suggestion if they make the wheel in that size

That sway bar has the factory type geometry and attaches to the stock LCA sway bar mounts? Hellwig made a sway bar that has kinks in it for additional tire backspace clearance.

IMHO, I'd go with the 245/50/16 16x8 5" bksp up front even if they rub a little at full lock to lock. You'll never be hard performance cornering at full lock unless you doing a Hail-Mary maneuver to correct a spin. You could even add 1/8 or 3/16" spacers if there is outside fender lip room. For extra insurance.

I've run 245/50/15 with 4.5" backspace without rubbing (but real close). The extra rim diameter of a 16" may help some.

Just me personally. I always want the biggest tire I can to grip corning and stop fast.
