Bandit Posted March 31, 2021 Report Share Posted March 31, 2021 Probably a silly question, but for some reason I am having trouble getting my head around this. These two wheels have the same offset, +56, width and diameter but the spokes attach to the rim differently. Will they exert the same force to the hub? I ask as I would like to run some spacers to push them out a bit, Camaro wheels have a better offset but not available in repros, and the thought that the spokes being all the way out to the lip on the first example may have more leverage on the hub. Not a huge difference I'm sure, but is there any? Quote Link to comment Share on other sites More sharing options...
Donovan Posted March 31, 2021 Report Share Posted March 31, 2021 To quote multiple engineering professors from my past- draw a free body diagram. But intuitively, I'd say spoke position shouldn't matter as far as your hub is concerned. 3 Quote Link to comment Share on other sites More sharing options...
EngEtan Posted March 31, 2021 Report Share Posted March 31, 2021 All things being equal (offset, width, diam...), the location that the spokes attach to the barrel does not change any of the forces applied to the hub. 2 Quote Link to comment Share on other sites More sharing options...
mhr650 Posted March 31, 2021 Report Share Posted March 31, 2021 As long as the center of the tire to the face of the flange is the same the hub will see the same loads. On my car I run very thick wheel adapters which would normally be bad for the hubs, but the Miata wheels have so much more backspacing that the tires end up in the same place and just barely clear the struts. What will make a difference is if one wheel is heavier than the other, for hub stress and everything else related to the suspension less unsprung weight is always better. 1 Quote Link to comment Share on other sites More sharing options...
Bandit Posted March 31, 2021 Author Report Share Posted March 31, 2021 Thanks guys. I figured as much but it's just one of those visual things that can be confusing. They don't list wheel weights but the tires are 32lbs. At least with the C7 hubs they went with the C6ZO6 design without the internal wheel speed sensor so they are pretty reasonable, around $75, while having a 1500 lb thrust rating so a bit of a spacer shouldn't be an issue. Stock hubs/bearings are only rated around 921 lbs so they are marginal with much less tire. Kinda like Miata hubs. Quote Link to comment Share on other sites More sharing options...
Black Magic Posted March 31, 2021 Report Share Posted March 31, 2021 We run similar wheels on the 230 SLK I help with (with adapters). The c5 Z06 repo wheels are lighter than the black ones you posted a pic of. Might want to look at them. We also use alot of spacer. 2400 lbs car, but haven't had a wheel issue yet. Even "modified" some with the wall and didn't break.... 1 Quote Link to comment Share on other sites More sharing options...

I know oewheels have been run on at least a couple heavy cars and they seem to hold up well per reports. For the price they are hard to beat when it comes to big wheels. Of course the proper backspacing would be ideal but then a guy is looking at $4-500 per wheel and they would likely need a spacer as well with standard, not the narrow, Superlites.
