I just talked to a Spacer manufacturer who said I needed at least 1 1/8 of thread on my current setup to be able to safely run 1/2 inch spacers.
It's very close, I'd say I have 1 1/16 of thread, possibly 1 1/8 when you tighen.
On the stock wheel and nut I get almost 13 full turns from on to tight.
Anybody running a 1/2 inch spacer on stock 20s on a 2wd for some time now?
I'm trying to see if I can run 1/2 inch spacers and 325/50/20s all the way around with no rubbing or problems.
