2005 lx470. I've been running these 1.5" spacers for 3 years with no problem. I now have a kid and am going back through all my sketchy decisions and noticed the nut threads about 90% of the way on (3/4 of a turn until flush). Is this a death trap? nut is 3/4" and stud is 1/2" so i got almost 1.5x of grab on them. I know the overall vibe of spacers is not great to begin with but want to run these until i get real offset rims.
