Wheel Backspacing / Offset

Discussion in '1979 - 1995 (Fox, SN95.0, & 2.3L) -General/Talk-' started by Daggar, Aug 24, 2007.

  1. How many "Will these wheels fit" threads have we seen?

    Too many for me to count! So I had this idea to make a sticky for just such a topic.

    Here is what we need:

    Wheel Name
    Wheel Size
    Back Spacing
    Spacer Size and brand (if used)
    Tire Brand
    Tire Size
    Fender lip rolling (Yes / No)
    Inner wheel well massaging (Yes / No)
    1 Picture of the side of the car
    1 Picture from the rear of the car
    1 Closeup picture looking down from the rear wheel well fender flare

    I'm going to leave this thread open for posting (as opposed to having these things PM'd to me)

    Please do not post anything in this thread OTHER than those items listed above and comments relating DIRECTLY to YOUR install of the items listed above.

    All other posts will be removed by either myself or other 5oh staff. I'd rather the user base took care of this thread and not have to lock it up for staff posting only.

  11. Hi i just bought a new 93' 5.0 GT and i want to do a 17x9 front and 17x10.5 in the rear but i wanna make sure that they are going to work. I am worried about the clearance of the shock that is welded to the axel rubbing. Can someone help me out i am looking at the Cobra "R" deep dish rims. thanks
  12. ...I think I'd categorize this as "Sticking Out"??? I have a 1.5 - 1.7" drop on my 88 GT using the Sportline Eibachs and if I had those mounted on the back of my car - the first hard turn I'd take the fender would be laying down on the tire.

    I niticed a couple guys mentioning which spindles the are using and that can make a big difference on fitment up front as well as figuring out what offset or B.S. would be needed.

  13. 1988 Mustang GT 5 Speed

    Front: 96-04 spindles. 17X8 Bullit's +30mm offset.
    Backspace: 5.72"
    Fender lip rolling: NO
    Tires: 245-45-ZR17
    Do they stick out?: NO

    Rear: New 1986-93 Rear solid axle. 17X8 Bullit's +30mm offset.
    North Race Cars Fox-Length Rear Axle Kit
    Backspace: 5.72"
    Fender lip rolling: Not yet, No
    Wheel Well massaging: NO
    Tires: 245-45-ZR17
    Do they stick out?: NO
    Do they bottom out?: NO

    Driving Notes: The front tires have just a tiny, and I mean very tiny small scrub under hard corners or a large dip or bump in the road. Again I have my car lowered pretty good but I also have not installed the new adjustable AGX struts and shocks yet - soon though. This will stiffen up the suspension and control the suspension travel to be much tighter which is what i want. This should eliminate the minimal scrub. I'm being very picky here.
    I also recommend that if you run a 9" or 10" wide wheel with a 275 width or higher tire out back that you purchase some aftermarket upper and lower control arms to tighten up the rear suspension. Most 5.0s stock control arms are sloppy at best with a 20 year old suspension. This will also allow you to ditch the quads.
    I also installed thye Eibach front and rear sway bar kit which is real nice and helped further tune a good handling tight suspension. Just some things to think about.
    Another direction that I urge 5.0 guys to take is using the 86-93 8.8 rear (not an SN95) if you want to run wider tires out back. Use the North Race Cars Fox-Length Kit which includes fox-length axles, custom laser cut brackets, and new e-brake cables.

    I am getting ready to order a set of 17x9 rear bullitts with a 275/40/17 tires. I have already test fit a 2003 Cobra wheel with this tire on it (see last pic). With the amount of drop my suspension has It will clear but again I plan to take this car on a road course and drive it hard. For safety I will roll the rear lip since it's a little closer to the lip than I would like. If you only drop your car about an inch it'd be fine. Being realistic and safe are a priority when doing modifications on my cars. I see so many people with 9 and 10 inch wide wheels that stick out and don't fit properly and I just feel that it not only looks bad but is not safe.







  14. Here's the New Billet Specialties Street Lite Drag Wheels on my 88 GT.

    Front: 96-04 spindles. 15x3.5 Billet Specialties Street Lites
    Backspace: 1.75 B.S. (with 7/16" spacers in the front only to clear the calipers)
    - For a little more clearance inside the wheel well, you could opt for the 94-95 spindles to move the wheels in about 3/8" each side, then go with a 1/2" or 9/16" wheel spacer and have a little more clearance without having to modify the caliper bracket.)
    Fender lip rolling: NO
    Tires: 165/80-15 Kumho Powerstar 758
    Do they stick out?: NO - just tuck inside.

    Rear: New 1986-93 Rear solid axle. 15x8 Billet Specialties Street Lites
    Backspace: 5.50"
    North Race Cars Fox-Length Rear Axle Kit
    Fender lip rolling: Not yet, I will just to make sure but these don't seem to rub either - surprisingly!
    Tires: 275/50-15 Nitto Drag Radials
    Do they stick out?: NO - Just tuck inside the lip!
    Do they bottom out?: NO

  17. i just picked up 03 cobra calipers and spindles with raybestos 13"rotors i also just bought 03 original cobra wheels .i will be doing a five lug conversion but i am curious any issues that i need to be aware of as far as spindles go are they the same from 94-04?what size tires can i go with that won't require me to roll the lips in the back?
  18. That's a negative. The pic is decieving. They did not stick out. A straight edge proved it.
  19. Can I see a straight edge pic please? To me it's overly obvious fromt the pic the tire bulges way outside the rear fender.

  20. Nice thread, Very helpful. Lets see some moar!
