Fox Mustang stocker wheel questions

[Doug Hoven]

There are foxbody stockers out there with 30x9 tires on them, but if you want to retain the factory width of an 8.8, I would go with a 28x9. Not sure on the backspacing. As far as rear suspension, I believe a set of aftermarket lower arms (I have BBKs on my street car), and a set of adjustable upper arms would be a good start. I don't believe you are allowed adjustable lower arms in stock. Some have used an air bag in the right rear, but a good antiroll bar set up works very well too.

Thanks for the info yes retaining factory width just trying to get correct backspacing to get it to fit

Pretty sure that the wheelwells on my 85 LX Hatchback were the same as a 87 thru 93 Mustang, I ran 9x28MTs, , 9x29 Hoosiers, and 9x29 1/2" MT slicks om my 85, using both 15x8" and 15x9" Weld Draglites, with 5 1/2" backspace. The 28" fit with no wheel opening modifications, the larger tires required re working of the lower front area. All combinations required some hammering of the inner wells for clearance. For rear suspension, I used Maximum Motorsport non adjustable lower arms, "Auto Weld" adjustable uppers, which also raised the rearends upper mount position, (similar to GM "No Hop" bars), and Strange adjustable rear shocks. I tried 4 cylinder, Moroso, and 5.0 GT rear coil springs, on my car, which was a stick, the heavier GT springs worked the best. I also used a rear sway bar from a later FOX GT Mustang, as well as a pair of Air Lift air bags, with seperate lines for left and right. Some guys just used 1 in the RR, but since I had 2 I used both, although with only 5 psi in the left bag, right varied from 20 to 35 psi. Not sure if it is absolutely necessary if you are using an automatic, but reinforcing the mounting points of the body is a good idea, they have been known to crack and rip out. Much better (and easier) to reinforce them before they get damaged, than afterwards. Again, not sure if it is needed with an automatic, but on my stick cars 8.8 rear end, I had the axle tubes welded to the cast center, and after bending the tubes, braced the axle tubes to the center, and used a load bolt aluminum rear cover.
