Are you torquing them right after the session when the car is hot?
Thats a big no no. heat expands and contracts. Should only be torqued when cold. When you hear about ppl shearing the lugbolts at the track, its because they retorqued the bolts right after the session when the wheels are hot. They become overtorqued.

If its after the car is cooled down, i agree with trying a different torque wrench.

I would have to re-torque each lug to 104 lb/ft. The lug might come loose again after the next 20 mins session, and I just re-torqued it again. After a few sessions, the lugs might not come loose again in most cases.

BTW, this same issue happened to me whether I was running stock 666 rims with stock lugs or vorsteiner rims with stock lugs. and it happened to all 4 corners. My car is 18" ZCP with CCB.

Has anyone experienced this as well? What's your solution? Or am I doing anything wrong?

Thanks.
