Re: 1/2" Wheel spacers?

You're only using 1/4 spacers, so I wouldn't be too concerned because the extra leverage placed on the stud is minimal. I've seen guys use 1" spacers (slip-on) and longer studs, and that's just asking for trouble because the wheel nut is so far away from the axle flange now that it put huge amounts of leverage on the base of the stud especially if these are installed on the drive axle.

I personally don't like the adapters. They are equally as bad if not worse in my opinion. With spacers you can at least check your lug nuts every now and then to make sure they are torqued. With the adapters the nuts holding them on are hidden by the wheel and you don't know if they loosen up... loose nuts could cause you to lose a wheel with both types.

Caveat:. I've never run either type.
I probably should have clarified what type of spacer I was going to use. Definitely, not the adapter type. It still allows for the lug nut to tighten all the way down the threads.
