is it bad to use wheel spacers?

I'll explain it better for you:

 

You know who wont have issues with wheel spacers. Guys asking about them on a forum. These are the people most likely to use proper torque specs and check them periodically.

To the guy who sheered his lugs....sorry to hear, but if the lugs all sheer off, that was gonna happen without spacers, someone over stressed the lugs at some point

 

Definitely could be, either way, they were professionally installed, and my wheel came off, so personally I steer clear of them.

 

Yes its bad, if its not close to oem spec its bad.

 

This^^^^

 

Adapters are one of those things that work well until they don't. It seams to be a gray area because some mechanics call them spacers which are illegal in a number of states while others call them adapters. I don't think it's the added force on the bearings or other parts of the vehicle. It's that cheap quality ones can break causing the wheel to fall off.

Yesterday I was watching a show in Velocity (or what ever they call themselves now) about trying to make a S15 do a faster lap. The truck had adapters on it to make the wheels not rub on the leaf springs. One of them was broken.

If you have the wheels already I would use good quality ones. If you haven't bought the wheels then I would just buy the correct wheels and not deal with them.
