Do not fabricate your own spacers.
Just my opinion as i do not like them at all. Had an engineered billet one crack then break on my truck a few yrs. ago.
Damn near lost a rear wheel and almost wrecked.
Was that a simple spacer, or was it an adapter to change the bolt pattern? I would think the adapter would much more likely to fail.
Don't get me wrong. I think the entire thread is insane. Where is he going to get 3 inch longer wheel studs anyways? I just meant to say that a single spacer is much better mechanically than 5 individual spacers.
