Updated: Found out I'll clear just fine with 1" backspace in the rears. Fronts are TBD, see below.

Also, my other fear is the 11s up front. I know people have ran 12" up front but needed major negative camber to clear. I dont want any negative camber at all if I can help it. Will these 11" work in the front? I'm really trying to avoid rebuilding them but will if I have to.

Here is my setup. Let me know if anything throws a red flag.

255/35 would be the correct tire size for the front. Just my personal opinion, but 11"/13" wheel width seems excessive for your intended tire sizes.

How did you calculate the rear? I am thinking you would want something around +40. Just looking at the large difference in offset front to rear should tell you something is off. I am running 11" +64 rear and there isn't an extra 1" clearance on the inside which a 13" wheel of same offset would require.

On that note, red flag? Yeah, the +23 is about an inch further out that commonly used 18x11s.

For those widths and fenders you'll probably want both front and rear around +35. You are way over-stretching those tire sizes, though. I have a feeling that's intentional but thought I'd let you know.

Well, I will tell you one thing, there is no way you are fitting that 13 +64 on the rear of this car. There isn't nearly enough inner clearance. You would need a hefty size spacer. That's fine if your accounting for that, but you didn't mention it.

295 on a 13 is going to look ridiculous, and not in a good way. 335 would have a hard time looking squared up. A little stretch is nice, but damn.
