I doubt there are any hub centric spacers that thin. I would say no, I'm sure others will say the same
I obsessed about this for a while, bought an adjustable track bar, adjusted it all over the place but never got it perfect. It changed every time I loaded the back full of stuff, put air in the helper bags, looked at it the wrong way. Overall it's really just not a noticeable or constant offset and probably not work "fixing".
i'm going to be installing spacers/adapters to push out my wheels a little bit.
but i wanted to get thoughts on using a thinner adapter (maybe .25" less or so) to offset the rear axle shift that happens when you lift the rear with no new rear track bar.
thoughts?
