You will need to roll your rear fenders to run 9.5 ET35 on the rear. They don't rub on Coupes, but do on sedans.
Check out an 18x9" with 41 ET in the D-Force LTW5. Or Modbargains offers a couple staggered set of CSL reps, like the VMR, or the Sportline 8S.
No, they rub on coupes too. Unless you're stock height.
I think Apex has a 18x9 now with profile 3. That would have made things a bit easier when I was fitting the ARC-8's on Brian N's sedan (the picture of the black sedan OP linked). Of course, back then, we had to do things the hard way and pioneer everything lol But we ran 255s. Even 255s are a little stretched imo.
