First, here's a pic of my xA so you can see what I'm talking about:

Seems as though the rims still look a little sunken in, so I was thinking about wheel spacers. however, I've never dealt with these things before, and I saw a potential problem that I'm not sure how I could fix. When the rims are on already, there is very little thread left when I put the lugnuts on...If a wheel spacer takes up some of the threaded space (not sure if that's how it works or not) then I don't think there would be any thread left to screw the lugnuts on securely. How do you guys get around this problem, if it is a problem at all (like I said, I've never dealt with spacers before).

Something tells me I posted this in the wrong section :(

Most of the wheel spacers I've seen come with longer wheel studs that also need to be installed and remember to only use spacers that have the center ring machined on them to keep your rims centered and if you aren't already using them, use hub-centric rings

theres thinner spacers that are like 5mm or so that will still let u have enough..
but sometimes u need new studs!

but heres a solution!

www.onetongarage.com

they have spacer shims, they space out the wheel
without touching the threading on the studs!

speak with VAN he's an awesome and helpful guy!
van@onetongarage.com

they even have a before and after picture on that site! goodluck

I use the one ton garage spacers as mentioned above they are the best they are hub spacers not wheel spacers ALOT safer.

Yea, but they only work on the rear!

The rear sits in farther than the front and is usually where people want to add some more. Van also sells some nice spacers on the Onetongarage.com website and has some great info on why you should avoid universal wheel spacers. I've got the spacer shims in back and love them.

If you need more in the front, you'll probably have to change the wheel studs. There's an article on how to DIY here:

I bought 20mm spacers for the rear of my xB and have had them on for about a month now with no probles. the spacers are hub centric so there was not much play at all in the spacer, and there were new studs pressed into the spacer. the only problem i ran into was the factory studs stuck out from the spacer about .25" and wouldn't let the rim sit flat on the spacer. i cut the studs off .25" and the rim sits flat. I drove to Georgia and back this past weekend and had no strange vibrations or anything. I have the 10mm spacers for van and might be using them when I lower the xB on the front if I have rubbing issues.

the only thing that sucks about spacers is that some tire stores will refuse to do wheel/tire work on vehicles that have spacers due to liability.

Yea, but with the one ton garage ones they'll never know you have them on. Especially if you paint them to match the rest of the axle

Thank you guys so much for the link...I'll get that before I put the rims back on in Spring :)

heres a little thing to help you with knowing if the lug nuts are safely on.. take the size of the stud (12mil) and divide it by the thread pitch (1.5) ie our lugnuts are 12x1.5, there you yeild 8 turns....so eight full turns of the lugnut will give you the maximum stregnth of the stud

brent

oh btw, the front has much more stud than the rear, so for sure u can run a 5mm in the front or 3mm or whatever if needbe and still be safe
