TORQUE stick - they are "cut" on a lathe(?) to only torque to a certain
amount then they will not
Sorry - don't really know the physics about it.

Not really - they usually do work depending upon how old and worn they
are. A good
friend uses them on Honda's - he is a mechanic - the dealership
BUT they require the Audi mechanics to tighten with a torque wrench!!!
Makes you think.

Not as serious but: I have Sears BFGoodrich tires on my SUV (lifetime
balance/rotate). Wife and I were going away for a long canoeing trip in
Northern Maine so I stopped in for Sears for a balance/rotate. Put my copy
of the service order in the glove box and bolted for the north woods. 21/2
weeks later driving back noticed the "Front-end shimmy-dance" when braking.
I knew exactly what the problem was and thought I might have cracked a
rotor on the Logging roads (second thought probably not since those puppies
weigh about 30 pounds each) BUT I did look at my Sears check/service list
and they tire buster torqued the lugnuts to 175 ft/lbs. when they should
have been 47 ft/lbs. Needless to say the Sears service manager was not
happy to pay for 4 new rotors at $175 each but he did!!! (Sears provides
torque sticks plus a BIG color coded chart to reference but I guess the
tire buster didn't want to check)
1. I still go to Sears (for the SUV) but I double check work (they only do
2. Just because its big doesn't mean it can't warp
