what size are the stock lug nuts?
 

jesus fuck, I need to buy a socket, and can't find this shit on google. 21mm?

and anyone know of a good deal on a torque wrench solely for wheel lug duty?

Walmart has torque wrench's for cheap. I'd use one of them for wheel lugs then just trade them out every once in a while if you felt it was out of whack.

I was thinking about doing that with a craftsman.

What size is the lug socket?

The outside of the lug nuts are 21mm.

I picked up a cheap 1/2" drive torque wrench at the Harbor Freight in Richardson, was on sale for $11.00...

thanks
