The other thing I may add (Hey Anthony) is once you torque the lugs, roll the car back and forth about 2-4 times and retorque.
Other thing is to also add a little bit (1/2 a pea size) anti-seize on each lug before putting on the studs. This helps make the thread engagement much smoother and you get a more accurate reading on your torque wrench.
I've torqued all my wheels to 80ft/lbs with no problems coming loose. And I've attended over 300+ autocrosses in 10 years. That's about 30 autocrosses a year where I would change my tires/wheels.
When I first started though I was having problems with lugs/studs stripping off and that's when people told me to do the anti-seize thing and start threading the lugs by hand the first couple of turns. Then use a impact gun to get them on/off quick.
