I am going to ther track Fri (2001 L) and my new rims and slicks use 7/8 lugs, but the stock lugs seem a bit smaller. Are the stock lugs 7/8 or 21mm? What is the recommended wheel torque? I may get a set of the torque sockets for both lugs and cordless impact wrench to make the swap at the track easy.

 

14mm stud and 150 lbs

 

I know the stud size, I need the lug nut size.

 

14mmX2.0 the actual socket size is 13/16 or yes 21mm i think
