i have a 93 sc400 and its sitting on supra tt rims. i am using tuner lugs. my question is that why after everytime i drive i have to retorque the lugs? they seem to keep coming off like it doesnt take enough of the threads. like today when i was driving on the freeway around 75mph, when i switch lanes i can feel the rear sway side to side a little bit. so i exit and i could still torque the lugs down to 80ft.-lbs. so does tuner lugs work with supra tt rims or do i just have to go back and use my stock lug nuts or do i have to go and buy supra tt lug nuts?
