Lug Nut Torque
This is just a heads up. You may want to check the torque on your lug nuts. I changed out my lug nuts today for locking lug nuts and found that the torque from the factory was all over the place. I found a few at 90-100lbs (100lbs is the recommended) but most were between 65-80lbs.

That's odd because a machine tightens them at the factory... The only way they could be under-torqued is if the operator pulled the machine off prematurely. They must be rushing these cars out-the-door because that would explain all the problems that people are having.

You should check your torque regularly regardless. When wheels are first installed, it is often the case they need to be re-torqued after a few miles. When I got my first M3, one bolts was so loose I could turn it with my finger

Factory Torque
I don't know how Bowling green does it but the Oshawa truck plant had a setup with a gang of guns that ran all the nuts up together. A computer monitored the torque. The nuts were run up to torque spec, the machine released from the truck and the truck would be released from the station. If the torque cycle failed, the operator would use a torque wrench and torque the nuts to spec, write the job up on the job sheet and release the truck. Specs were pretty tight. They certainly wouldn't be all over the place as in this case. I'm in the process of changing to my other set of wheels and tires. A couple of nuts were just a little low on torque and I always use a torque wrench. It pays just to go around the car once in a while and check the torques. It wouldn't take five minutes including getting the torque wrench out and putting it away.
