wheel stud problem...

YIKES!
Spacers will push your tires out...most likely hitting the fender on turns, turns onto driveways for sure!
But more important.....would I trust the safety of the spacers.....NO! I would source another way....Just my 2 cents... (2 cents isn't much these days and no pennies are used in Canada, we did away with the penny!) LOL
The rock crawler guys run 2 inch spacers and beat the hell out of the rig all day and no breaks. :D
Spacers/Adapters are fine as long as you use billet or steel ones and not the cast aluminum crap
