11" wide rims on rear 67/68/

[Coleman]

I would go 6" back on a 9.5 if it were me. Then 5.5" back on a 9. I did build both of those cars above (black and Red) we use a 17x11 with a 7.25 backspacing. We now narrow the rear and give the wheel more lip.

First off, the cars you built are sharp! I love the stance, esp the tire size on the rear.

Did you have to "mini tub" or add fender flares with the 7.25 bs?

I am using the prefabbed rear from TCI that is slightly narrower than stock and does not use rear springs, I was hoping to stuff the 11" rims and tires under there. (I will post the exact width from face of disc rotor to face of disc rotor) I have already rolled my quarter panel wheel openings.

I did order my wheels, but was told they would allow returns if I do not mount tires.

Thanks for the information!

I dunno about that.... both Rick and I used 9.5" wide with 5.5-5.875" BS and in both cases a 275/40 tire contacts the front lower inboard corner of the inner wheelwell to an extent that a BFH needs to be used to reshape that area of the inner fenderwell to prevent the interference. A full 6" BS wheel would only pull the wheel in further.... creating even more of an interference.

Is CR widening the rear fenderwells when using an 11" wide wheel? Personally, I can't see how an 11" could ever fit in a stock wheelwell. What about when using a 9.5 wheel with 6" BS?

A 9.5 is your max providing you are using a 4 link, if you keep the leaf springs 9 is pushing it but keep the 5.5 backspace. Guys always try to go to big and have tire rub. Rich.

Thank you :ecit
We do use a 4 link made by TCP and use an offset front bushing used for years on street rods. This pulls the lower arm in enough to have no tire rub. The control arms are also adjustable so we move the wheel back and then adjust the pinion with the uppers.
The red car is very close! Almost scary close because it has no flares other than a metal very small flare we made for it.

Rich,

We used a 17x9.5 w/5.5BS wheel and 275/40/17 tire on my son's '68.... and he has a traditional leaf spring suspension. There is NO tire rub under any conditions.

Dave,
I use a TCP coilover setup in most cases and able to adjust the wheel back if need be. Thats probably why mine works with no rubbing.

Yes we modify the wheelhouses if we run the 11 inch wheels.

I pulled my invoice from bunik the other day so I could order a new center cap, my rears are actually 5.75" BS. They fit without any issues, I did use a BFH to give a little more clearance.

A couple pictures

Before (about the width of my finger, maybe .75" of clearance)

Here too I personally don't see any reason to go much larger than the 16".... I like the Vintage 45's in that diameter and 8" width is fine. I fail to see why people stuff large wheels on these 67-68 Stangs... I must be just too OG :rtard. Leave the large diameter wheels and low profile tires to the newer models and the gangsters in monster mudder shows. :rtard bj

I have 17x9.5" wide TTII's with 5.75" BS in the stock wheel house and leaf springs. I using 274/40/17 tires. I haven't yet messaged the lower lip. All is well on normal driving but when I get aggressive on corners I can hear it rub so the BFH is needed.
I like the look but have no issues with 15's or 16's either.

I have 15x10 wheels in the rear with a 5.75" BackSpace
I cut the lip off the inner fender near the frame and rewelded it, then we rolled the outer lip of rear fenders.
The rear end is a stock width 9" with stock location leaf springs and ladder bars.
The only time it really rubs with the current Mickey T tires is with 3 people or more, but I usally am alone or there is only 2 of us.
The old PROTRAC tires I had before didnt rub at all, they had a squared off tread to the sidewall, the MT tread is rounder as it goes to the sidewall and thats the part that rubs.
If I go any wider it's gonna get some really really big tires....but that wont be for a while.
