AdreView Posted October 25, 2013 Share Posted October 25, 2013 (edited) If you look at the bolt holes you can see a previous owner drilled them...well...IN toward the bore. Plus the rear bore opening was also drilled out sloppy on 2 of the 4 wheels as you can see in the pics. I have not a chance to measure but there is a 4x114.3 pattern in there as it test fit on my '78 280Z. If I go ahead and use these as is, would I be taking a risk in safety or should I bring them to a welder to fill in the holes and redrill to the correct pattern?

z240 Posted October 25, 2013 Share Posted October 25, 2013 No way in hell I'de use them as is. Looks like scrap aluminum to me. Unless the wheels are very special to you, the cost to have a wheel refurbishing company fix that is WAY beyond the cost of new ones.

RebekahsZ Posted October 25, 2013 Share Posted October 25, 2013 If you use a washer and heavy shank lug nut system like you would use with a weld draglite, you'd probably be fine. Torque them with a torque wrench to 90# on a regular basis and let it rip. You should be able to feel it in your hands or butt if the tire is out of true to any significant degree.

Unless the wheels are very special to you, the cost to have a wheel refurbishing company fix that is WAY beyond the cost of new ones. From a structural/safety perspective, why would you not attempt to use them? If you use a washer and heavy shank lug nut system like you would use with a weld draglite, you'd probably be fine. Torque them with a torque wrench to 90# on a regular basis and let it rip. You should be able to feel it in your hands or butt if the tire is out of true to any significant degree. This is what I was thinking the last owner did, shank lug system which would have to be used to secure it properly. Many folks these days are redrilling customizing and modifying sizes of wheels to fit on all sorts of sized hubs, I'm thinking this wouldn't be mush different. Since there is plenty of material on the wheel bore, I'm thinking of just having a welder close up the current twice drilled bolt holes and have a local machine shop redrill new ones at 4x114.3 just to be on the safe side.

morbias Posted October 25, 2013 Share Posted October 25, 2013 Yep, jack the car up and make sure the wheels are spinning straight and are centered; unilug wheels are nothing new Quote Link to comment Share on other sites More sharing options...
socorob Posted October 25, 2013 Share Posted October 25, 2013 Are you sure they are drilled? I have seen a few sets like that over the years, and I doubt anyone would be able to drill a hole that accurately that close to another hole at home. I think some wheels used to come like that.

I really have no history of the wheels and if they came this way or not. I was thinking sort of the same thing, every drill cut I have ever made to elongate holes never turns out good, these wheels appear damn good for elongated holes. They resemble a model of centerline, the only info molded into the wheels is: PRO WHEEL 14x7 I've searched for similar pictures of them and all I can find are these, which don't have an elongated bolt hole: Quote Link to comment Share on other sites More sharing options...
socorob Posted October 26, 2013 Share Posted October 26, 2013 As morbias called them unilug they were made to fit 2 different bolt spacings. Basically a universal wheel. The wheels on my Z have the same slots. Quote Link to comment Share on other sites More sharing options...

m1ghtymaxXx Posted October 28, 2013 Share Posted October 28, 2013 It looks like the "two holes" are different diameters, so that must help center them, otherwise I would have thought the slots would need to fit rather snug to the studs to keep the wheels centered.

SlowRob Posted October 28, 2013 Share Posted October 28, 2013 As long as your lug nuts don't have any slop radially, they will naturally center. If there is slop radially - side to side - then they won't work. The slots aren't an issue because they only allow movement in one direction for any given opposed pair. The perpendicular pair fix that movement, causing the wheel to center. Quote Link to comment Share on other sites More sharing options...
