305's on the rear will be fine(20x10.5). The fronts might require a spacer

I went with Factory Reproductions, they have the backspace and offset perfect for the 9.5 with the 275 on the front and same with the 10.5 with 305 on the rear. They know what they are doing. One of the best suppliers you can go with. Their wheels pass certifications JWL etc.. as well another reason I chose to go with them. Oh and their finishing process is top notch too.

Those are Widebody replicas BTW ;)

A Guy
and by the look of the position of the wheel you have at least a 22 offset maybe even closer to 18 on the rear. It's set more for the widebody with the wheel positioned further away from the car. You want the wheel tucked in further for better clearance with the fender. At least that's what it looks like from the pic.

Only pointing that out should someone else want to go that route. You can contact Factory Reproductions directly and they will get you the offset for how you want the wheel positioned. If you run lower you will have clearance issues with the wheel positioned outward.

The Widebody rims are +15 offset front and +22 offset rear if you do a staggered fitment, same offset as their Demon replicas.. They only come in one offset per size of rim. This set up is 275 fronts and 315 rears-Demon replicas. I say its flush with the fender. The yellow protectors are no longer on the car...

yeah yours are definitely flush/tucked up under the fender. I went with 15mm front with the 275s and 25mm rear to run 305s. I assume the 315 need the 22 vs 25 to clear the inside wheel well. Those actually fit really well. I thought for sure the 315 would hit the fender, I was told the same too. Did you have to roll the fender?

No, didn't have to roll the fenders. But you are correct, people were having problems running a 315 on a +25 offset rim. That's why when Factory Reproductions came out with their Demon Reps, they went with a +22 offset.

That will be good swap. Just curios what is the offset they set you up with?

It looks more flush with that pic and I zoomed in. Just the angle of the other pic made it look like it was set out further. Or my eyes are just going bad.. lol

Ah okay so they do stick out. After seeing the 22 offset on Dodgeboy90501's they should be flush. if you do the math based on a 1/2inch I'm thinking maybe you have 15mm offset on the rear.
