So there are some people out there that have probabaly already figured this out but I thought that I would share my little discovery!

I have a 1969 Barracuda that Idearly love. I hated the wheels that were on it when I purchased the car and set out for a new set. Finding that the 4x4 bolt pattern was a challenge I did some research and discovered that the 5x100 bolt pattern is the same....and there are a ton of wheels out there that are 5x100.

It took a little time to find some that had the correct back spacing but I did and there were multiple choices.

I went with a 16x8 and ran a Nitto 555 Drag Radial under the back. It runs great and handles well.

Best of all I paid less that $400.00 shipped for new wheels on Ebay!

I will try and get some pictures of them so you can see what you think of my choice.

Have a good one everyone!
 
thanks for that. i was just about to ask what metric size was the same as the 5x4.
 
There are some older front wheel drive GM wheels that have a very similar look to the Magnum 500 wheels, but are the same (very close) bolt pattern as the 4" Mopar pattern.

I have known of this for years.
I just felt there were plenty of other options out there than to run the risk of a wheel tweaking and cracking studs.
They DO bend the studs if you do this, found out when I tried one of the metric pattern wheels, then went to put a small bolt pattern Cragar S/S back on the car.
Had to replace all 5 of the studs to do it.

Mark.
 
I was of the impression that the slight difference between 4" and 100mm would be detrimental to your studs, maybe even bending them.

4" = 101.6mm

I took a brake rotor home to try on my Dart. It "fit", but rubbed against the edges of the studs. So if you tightened a beveled lug nut up tightly, the stud would kinda bend towards the hub. It might even make wheel removal difficult, with the studs now bending towards center.

Maybe with the right rims, this wouldn't be a problem, but I'm not going to try it.

But I can tell you which newer cars come with a 100mm bolt pattern, if you need to know.
 
I did not find any problems or tweaking at all when I put the wheels on. I was able to thread the lug nuts on all the way when I first put the mounted the wheel. It lined up great!
 
Ok, this is the only pic I have at work. i will try to get more when I get home. Its not a close up is the only problem...





One note, it was a CLOSE fit for the spindle cap. The centercap actually hit the pin that keeps the spindle nut cap on and I had to meve it around alittle.

Did you have to remove the grease/dust cap to get the wheel to fit?
 
dude if this is true you earn the genius of the day award...i broke down and bought whelel adapters from summit. they cost only 160 bucks but the space out my cragars a lil to far so they rub on the inner fender...

I just figured out that you can click on the picture and it will take you to my myspace page where the picture is alot larger.

Have a good one all!
 
This subject has been around for years,and the genereal consensus among the Mopar community is that it is a bad idea.It is close,but not the same.
In my book there is enough small bolt rim choices to do it right,or go to big bolt.
 
I'm running this right now... so I can give you first hand experience.

The wheels you find in 5x100 are around a 35mm offset, when what these cars should have is around a 15mm offset.

The front fit fine... however the bolt pattern is slightly different as others have said... the studs are clearly a little tweaked once everything is bolted down tight, and it's really hard to get all of the lug nuts threaded to start... but it DOES work... I don't experience any shaking or issues.

Now.. the rear does not fit without a spacer... I bought a 1" wheel adapter spacer, from 5x4 to 5x100, so there will be no issues like that of the front.

The adapters cost about $60/pr, and they are thick enough to correct the offset. I didn't install them on the front because I wanted a narrower track on the front, but if you don't care about that I would just use adapters all the way around... they will fit properly, and it opens the doors to 5x114.3

Well, it may end up as a case by case or wheel by wheel situation. I found a set of 16x8's with 4" back spacing. Most are the 35 mm off set, mine are 0. I didnt have any issues at all and due to my back spacing I did not have to purchase any spacers. I just wanted to toss this out for piople looking at options and hope that it will help someone.

Thanks everybody for the input!

I think your wheels are EXTREMELY rare... either that or they are actually 5x4.

I'm not aware of a single car that takes 5x100 and an offset like you describe.
 
So what vehicles have this pattern I need fronts that go with my K.H brakes I was hoping to find 2 magnums
 
My calculator says 100mm is 1/16 inch wrong, undersize. If the 100mm wheel have holes for 1/2 diameter studs, our mopar 7/16 studs would relieve some of that difference. Then acorn nuts will either bend the studs a tad in a good solid steel wheel or maybe distort the acorn seat in a aluminum wheel.
If they run out true and stay tight... happy motoring.
