We torque the rears @ 100 and the fronts @ 75. That should be plenty for your car.

Wow, on that small of a stud? I only torque my 1/2 studs to 70lbs on the rear and 62lbs in the front.

I torqued my old 5/8s to 90lbs.

yes theyr Weld Pro Stars. but i believe it is the thread, pitch and length of a bolt or stud is what indicates the required torque value; not the brand of the wheel !

Honestly, for the smaller studs, you could do 75 all the way around, but we like that little extra for the back just to be safe.
