    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
    Offset
    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.

    Thanks!

    No pics of how the rear wheel sits in the wheel well, but it is in just enough so that the wheel doesn't rub the fender.
    Oh and by the way Eibach prokit with ES islolators.

    That would be good! :nice: Your post is not gone, only hidded until you're ready to post the info. Just drop me a PM when you're ready. It doesn't do anyone much good without the details of the install.

    You may want to add if there is any spring drop done on the car as well.
    I will post my car up when I get all the pics required.

    ...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.

    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.

    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

    That's a negative. The pic is decieving. They did not stick out. A straight edge proved it.
