Do 5x4" rims fit on a J-body

Sunday, July 19, 2009 6:54 PM

I know it's not an exact fit, but it's so damn close. Less than half a millimeter which is barely the width of a couple of sheets of paper. I have 4 mags made for an early 1970's Duster with that early bolt pattern and they technically fit (I tested). But will it break the lugs on the car?

what about the backspacing/offset? rwd wheels are usually a whole lot different than fwd.

Mr. Quick

Not only is the backspacing going to be wrong, and the hub bore is most likely different, but you're talking almost a full millimeter off per stud. A 5x4" pattern is 5x101.6mm, so the total difference is 1.6mm. Divide that by 2 to figure out how much each stud is off from the center of the hub, which is .8mm. Assuming the hub bore is actually larger than the J-body hub, and not smaller, you're stressing the piss out of your studs if you put those wheels on, even before you take into account the fact that they're going to be pushed out too far on the car.

I know, but I like the negative offset of RWD better than positive. I'm oldschool that way. May hurt ultimate handling, but probably won't interfere with every day driving. I hope...

Mr. Quick

How it looks or affects handling is the least of the concern. Read everything I said about the fitment again. The negative offset (actually probably more like zero on those rims) is just another factor putting too much stress on the studs. When you put all those things together, it's not a safe setup. For all you know, they're not going to fit anyway, because the hub bore may end up being smaller on them.
