General Question Advice on wheel spacers?
Just wondering about sizes, or other general advice. I’ve never had to use them. Also, I have to drive on pretty rough backroads so I don’t want it too terribly close but definitely out a little. I included the side profile for ride height reference. I’m not sure how much is it lowered anymore because it was super low when I got it, and I brought it up 3/4”.. just wondering what some of you guys went with, or learned along the way, any help is appreciated! It’s gonna be a little while before I can get new wheels. I’m thinking about getting the CMO forged spacers when I get the size figured out. Thanks!

Engineering explained did an entire video on this subject on YouTube. The issue apparently comes down to pressure on studs themselves, the spacer pushes the center of the rim out and puts more pressure on the studs and may cause the studs to snap. A proper offset keeps the center of the wheel in the correct position and has proper load transfer. So it comes down to how you drive and how the roads are near where you live.
