Can anyone help with wheels?

[n.e.mich]

Looking at these for my '94 cobra.
Summit SUM-521-5166PS25 - Summit Racing® Fast-Five Wheels - Overview - SummitRacing.com -REAR
Summit SUM-521-5765PS - Summit Racing® Fast-Five Wheels - Overview - SummitRacing.com -FRONT

Does anyone know of any fitment issues before I buy? (backspacing, etc)?

Thanks to anyone that can help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

For a rear wheel on a Mustang, usually you go with a 15" x 10" with a 6.5" backspacing, and the bolt circle is 5 x 4.5", which is the exact wheel you have listed for the first link. Most people run a 3.5" wide rim up front, not a 7", so I'm not sure what the backspacing would be for the front.

OK thanks Kurt.
I don't really want the super skinny wheels on the front though. I have been searching and can't find any backspacing specs for a 7" width.
Thanks,
Wayne

I also noticed in the specs the wheels are NOT hub centric. If the wheels are for racing I would think you would want hub centric for strength. not a big concern for the street though.

All the weld style racing wheels are not hub centric. I know it sounds like it wouldn't be as strong, but that's the way it is, it's basically what everyone uses for drag racing. They take some time to put on and take off compared to a hub centric wheel, and it's real easy to break a wheel stud if you aren't careful.

I noticed that as well, aren't there spacers with centering rings available to eliminate that?

There may be spacers that are hub centric to the hub, but it's not going to be hub centric to the wheel. The Weld style wheel doesn't have anything for the hub to fit into. It's really not that big of a deal anyway. It's a mag style wheel, so the lug nuts hold it in place just fine. There are guys with 2500hp cars running wheels like that, so don't be too concerned with strength. If you have stock brakes up front, you are going to need some sort of spacer there anyway. I think I got a 3/8" spacer and clearanced the caliper frames a little bit when I had stock brakes.

OK thanks, 3/8" spacers on the front. Any for the rear?
When you say "clearanced the caliper frames a little bit", what exactly does that mean?
Thanks for the help Kurt.

Revhead has a good point - Wayne is trying to fit a 15" wheel on the front of a 94 Cobra. The front wheels will NOT clear the Cobra brakes. Those front brakes require a 17" wheel with stock backspacing.
If the 3/8" spacer is enough, you'll still need to do a bit of grinding on the caliper and/or bracket to get it to clear the wheel. Keep that in mind.

 

[revhead347]

Sorry, I wasn't paying attention, I didn't realize you had a Cobra. You can run a 15" wheel up front if it's a 3.5" and you run a one inch spacer. I don't think there is any way you are going to get a 15" x 7" wheel to fit up there.

Hmmmmmmmm, confused as ever now!

I really just want more narrow wheels on the front(currently has '95 Cobra R's). All of the wheels I have found for sale so far are wide also.

Would really like to find some chrome 10"(or so) wide for the back and some matching 7" (or so) for the front.

I'll keep googeling!

Thanks to everyone for the help so far!

If you want a drag style wheel that works on a Cobra, the best bet is a CCW style cast wheel. Summit makes a knock off of those also.
