12 inch wheel guys
12 inch wheel guys Any one have any info on running a 12 inch wide wheel on a 4th gen? I've been thinking about it lately but never see anything on it. what are the benefits? Can I run a 29.5x10.5 inch tire on it or are they only used for W tires? What backspacing does everyone run with these? Thanx again for any help on this one.

In the process, got the wolfe tubs sitting at home and cut one of the wheel wells out already
Is anyone running a 12" wheel in an f-body? I am looking at going with a 12" wheel when I minitub the car in a few weeks...I'm looking for:
- Rearend shorteded & how much
- Back Spacing on the wheel
My 9" is narrowed 3" per side and I am looking at running 12" wheel with a 6.5" BS. Thoughts?

I honestly dont see why you would need a 12 inch wheel besides for the looks. If the car is set up correctly suspension wise a 10.5 inch tire would be fine.
Heck look at the times these guys just set in the Dragradial class at BMP a few months back. That Turbo Mustang went like 7.90's in the low 190's .....Sick

Somebody on here previously said you don't want the rim to be bigger than the width of the tire itself. I guess you wouldn't to run a 12" rim on a 10.5" tire if that makes any sense. I was going to order 12" rims and then decided to stick to a 10".

at a guesstimated 3000lb race weight, that car is making roughly 1600rwhp'ish according to an ET calculator. that mph should be enough to push a 3000lb raceweight to run in optimal conditions 7.2X to 7.1X. yes, 7.90 on a drag radial is a great accomplishment. however, with a properly setup, probably fully tubbed monster slick, the car would run sooo much faster. so, if you're not building the car for class rules, but just to go fast, get the fattest and tallest tire under the car that you can for the biggest footprint, just make sure you're geared for it though.

We have run a 12" wheel with 29.5x10.5's all last year... The car was more stable with the wider wheel. This particular car went 5.20's on a 12" wheel set-up and 10.5's...The class we run in decided to go to a 10" wheel rule...or we would still be running the 12.
I don't want to argue about why running a 12" wheel is/isn't better. I just want to hear the rearend/wheel specs of the setups for the guys that are actually doing it on an f-body.
Everyone has thier own opinions and ideas on the subject. I can tell you what we suggest for our faster cars and what we recommend. Faster meaning low 8's to high middle 7's on a 28 or 29 tire that is 10.5.
We use the 12" on 28x10.5 as well as on the 29.5x10.5 MT Slicks. It provides a slightly larger footprint on the starting line. It also provides more stability on the big end.
We also use a 12" rim on the 325/50 and 315/60 BFG or MT Drag Radial.
We have run all those combinations on stock suspended cars running the the 7's. We alway recommend if you can fit the 12 then run it.
And for the record on our shop cars 7.53 run on drag radial, it was on teh 315/60 MT drag radial on the 12" rim.

I second this!

Pictures of wheel and from behind?
Awesome, thanks for the info. Did you have to do anything with the PHR mount to make it work?

I cut mine right up to the mount, i still need to but a brace on it more than likely, the car didnt see the track yet so i am not sure.
Looking for more combo's on this setup guys. Seeing if anyone else is running it this year lol. And I believe my rearend is shorted 2.75 per side so what would I need? And it is minitubbed with the wolfe kit
