315 in the back(tires)

[mustangsally93]

What all do you need to put 315 in the back of a 93 fox? I'm plaining on upgrading to the baer brakes and 5 lug 31 spline axles. I don't want to tube the the car. Do I have to flare the frenders? What about control arms?

Thanks.

more room!

Get rid of the quad shocks,so probably new control arms. hope it isn't lowered. Someone was running 315's with the tails still on but most get rid of them because they will rub. Do a search, I can't remember who it was that ran them.

probably will depend on the brand you run. Nitto's run small, so running Nitto 315's would be close to running BFG 295's I'd estimate (I've heard Nitto 275's are like BFG 255's, so I just did the math).

I've only seen one picture of a fox w/ 315's. I think it was a coupe, white if I remember correctly and those tires are HUGE!. I think he had to mini tub it. My 275's rub a little (I think on the inner fender w/ the back side of the tire) when I go up a very steep incline at an angle w/ any speed. BFG 315's are almost a full 1.6" wider than my 275's, so have fun w/ that. I'd assume flaring the fenders will be mandatory.

The only way to get around mini-tubbing that I can see is if you used a small backspace and had the wheels stick out from the fenders like an inch and a half, which would look stupid in my opinion.

Hissing Cobra has 295 BFG's on the back of his 79 and I think all he had to use was an air bag on one side, so that might be an option w/ 315 Nitto's, but 315 BFG's will probably require more than that.

Good luck

I also beleive keeping the Fox rear offset is vital to even being close to running that big of a tire depending on what wheels you go with.

The baer setup does push the wheel out slightly, but not at much as SN95. If you want rear disk, a Cobra setup using North Race Cars brackets and Fox-lenght 5-lug axles may be in your better interest. Cheaper too

a MIRACLE.

I'd say just about all the big dog cars you see with 315ish size tires out back are probably mini-tubbed.

it was bert306 that had the 315's on his car, also hatchbacks have more room than notchbacks in the rear and convertible wheelwells have the least room

I own a 93 convertible and a 96 Cobra. I put Goodyear GS-D3's in 315/35 on 17x10.5's on the Cobra and I'm here to tell you that there is no way in hell that they would fit on the 93 without major modifications.

That's one of the best thing about the '94+ cars is that they can handle huge tires.

Ok, noob question. What exactly does mini-tubbed mean??

tubbed means you've cut the rear inner fenders out and welded in "tubs" which are basically just wide sheet metal humps so that the tires can fit under the car without rubbing anything. mini-tub is just a smaller and less serious modification. Typically if you have a car that runs the big slicks in the back, that's usually the full tubbed and totally custom rear end. On a car like ours you can minitub and just cut out the inner fenders without doing anything to the suspension.

This car has been mini tubbed, but also has a custom suspension and shortened rear axle in order to make those huge steam rollers fit under the fenders. That's a bit of an extreme though...you won't fit tires that wide under your car unless you relocate the control arms and really do a custom suspension yourself.

There is a thread somewhere on here that a guy did with a blue fox and tailpipes and ran the 315's with no tub at all. He ran the Nitto DR, because like said earlier they run small.

Heres the thread

I found the thread but it really say nothing how he did it other than ranger axles and cutting the in side of the frender. I was hoping for a more detailed walk though. I'm not going to be running tips just a 3 inch down pipe. I was going to just do the 5 lug and put the tires and rims on and then take it to a body shop and have them flare the frenders around the tires.. What about that?

Thanks

I would shoot him a message, and see how he did it.

Yea he has to be gone. His pm box is full.

The baer setup does push the wheel out slightly, but not at much as SN95.

Baer = .20" each side
SN95 = .75" each side

 

[mustangsally93]

I guess maybe a custom rear end and a little body work.
