Lug nuts

[BoulderVette]

Uh, what size socket fits our lug nuts, our being a 2004 Z06?

[FOXBAT]

12.5 mm x 15. 12.5 is the diameter; 15 is the thread cut.

If you are talking about the outside of them. A 19MM or 3/4 inch socket work for me. Don

Got your decimal in the wrong spot. It should be 12.5 X 1.5 Don

19mm socket fits the outside of mine.

If you've got the originals, they're the crappy tin-covered nuts ... several get the solid McGard or Gorilla replacements.
Get a deep well socket; else it won't seat and you'll end up with ridges on your nuts

Ouch!

These are replacements. Look like Gorilla's to me. Definitely plan to get a deep well socket, and have an extender for my torque wrench which leads to another question, what's the torque spec on the lug nuts? Can ya tell we're autocrossing on Sunday!
