Another "Will these fit?": 18" Mustang wheels

So in the front an 18x9 +24 should fit with a 255/40/18 as long as you stay with the 73+ mopar disks. That combo should be about a 1/4” inside of the 275/35/18’s I run on my car. I have 18x9’s with a +35 offset, but I run 13” disks that widen the track 5mm and I’ve run a 3mm spacer so that’s effectively a +27. I don’t think you’d clear 275’s but 255’s should work. With 18” rims the tie rods fit inside the lip of the rim, unlike a 17”.

In the back, what year is the B-body rear? It makes a difference. Also, are your springs in the stock location? I have a 68-70 B rear with 1/2” offset springs, my 18x10s are a +38 though with 295’s.

***Edit***
In the front you will most likely have to either have the wheels machined to enlarge the hub bore or have the hubs on the rotors turned down some to clear the wheels. I had my enkei’s machined to clear the hubs on my rotors.

Dang I didn't know 275s could fit on the front but yeah I'd rather not have to use spacers and such. The rear I have is out of a '67 Coronet it's definitely an earlier one, not a '71-up I know those are a lot wider. I had the spring perches moved 1/2" inboard on each side to line up with the A-body leaves. I think I'll have all 4 wheels machined to fit the car because I tried to test-fit a friend's 18x9" SVE Mustang wheel and it wouldn't clear the centering hub even on the rear axle flange.

The car currently has 15x8" Rallyes with (I think) 4.625" backspacing and 275/60-15 tires and they rub the fenders in hard cornering or over big bumps. I looked up the specs on the 10"-wide version of the wheels I linked and it says the backspacing is 6.37", according to this online calculator that should move the tires inboard just about the perfect amount (0.75")... There's at least an inch of room between the inner sidewalls and the leaf springs currently.
