18" Wheel help
Interesting.
I've always planned to go with a square setup but things keep pushing me in the direction of a staggered setup and this adds a twist I hadn't thought about before. Thanks.
I know you're aware I'm a bit of a "wheel hound" so I have spent entirely too much time looking at wheels and considering my wheel and tire options. Like, WAY too much time.
If you want to run square with big wheels, you can go up to 18x10 and a 285/35/18 with work on the front fenders (rolling, flaring, brace extensions) and a 1/2" spring offset in the rear. With that set up you'd be best off with a 65-67 or 68-70 B rear and your 18x10's with offsets in the +30 to +40 range with the wiggle room being what disk brakes you're running and maybe a small spacer.
After I did the "reverse tub" on my Duster and started looking at 18x10.5 up to 18x12" wheels I figured out pretty quick that 18x10 is the break over, from 18x10 up there starts being a lot of lower offset wheels. That would go for mini-tubbed cars too. So for those, the A-body width starts making a lot of sense again. So if you want 295's or bigger it kind of switches back. There are a few Mustang wheels that are like 18x11 or 18x12 with big offsets, like +48, but only a couple of choices in that kind of set up.
Thank you all for the replys, I was hoping to keep the rear end stock and just put a nice set of wheels/tires on, lol
I see that is harder than anticipated. I am not much of a fabricator so i was hoping i didn't have to relocate any brackets/mounts etc.
I guess i may have to do more research and see if maybe moving the springs is the answer.
I'll keep searching and i'm sure i'll figure something out.
Thanks again for the help! Great group of guys on this forum!
Yeah it gets a little tricky because of the track width difference on the A-bodies front to rear with the A-body width 8 3/4. Actually gets weirder if you have a 7.25 or 8.25 BBP, because those are even narrower so you need like a +30 in the front and a +0 in the back.
To truly run square with like an 18x8 up to around an 18x9.5, or a stagger within those sizes, you'd want a B-body rear axle, so you could run a +25 to +35 offset all the way around.
