Yes makes sense, though it seems like, if you look at the design of the
rotor as well as how the rim bolts to it, that this wouldn't warp the
rotor? Though what else could it be?  I also noticed that after
tightening the lugs with an impact tool, they then, by hand used a large
bar torque wrench on the wheels, so i was told to achieve 125lbs.

It's amazing how obsessed they are about liability and putting anything
on that is not stock etc. but then they hire clueless kids who
apparently don't pay much attention to properly installing things? You'd
think we were a third world country... i saw a lot of this when living
in Latin America.
