In reading the Shelby Maintenance schedule under the GT500 insert for tires and wheels I noticed it was required that these aluminum wheels be retorqued at 100psi after 500 miles. I must say I have never done this before but felt if the manual says it should be done then so be it. Well to my surprise all lug nuts, except locking lugs, required at least 1/4 turn at 100psi.
The significance of this may not be material, but I feel uneven torque on these wheels could be significant given the power we are dealing with. For those who have not done so you may want to give it a try. I used a SNAP-ON torqure wrench in which the calibration was currently certified, and is good to 150psi, for those who may have there doubts. I should mention that I did this procedure after 1100miles
