For those of you who run wheel spacers, how often do you remove the wheels and retorque them. I retorque them, but not on a regular basis, mostly just when i have a spare 30 minutes. Thanks.

I re-torque after 50 miles then again after 500. At this point the torque setting seems to hold and they can not be tightened further.

pretty much same here, I hit them about 5 days after install and barely got them to budge.
The loctite is holding well...

I use loctite 271 and only retorque them once after 50 miles or so, haven't had any problems. Just went to pull one off and it was a PITA cause it was tight and the loctite was holding.
