Yep, it actually did it twice. put the spacers on Sat evening and made 2 small trips and it did it's thing 50 yards out of rht driveway. then Sunday morning all seemed OK on the way to the store. but on the way back it went crazy again so I took them off after that. I thought maybe it had something to do with jacking the car up one side at a time but nope. Anyway, I didn't feel comfortable with how little threads it left me available with the spacer anyway. they are pretty thick. I think something like 5/16 and I could only turn the lugs about twice before they made contact with the rim so forget it. even with them on, the rear wheels still didn't stick out as far as I hoped. It's cool, I can live with them like they are.
