Locking lug nuts
 

I just bought a 2017 xe ,I wanted to put on a set of locking lug nuts but I'm getting different info on different sites one say 12mm x 1.5 and the other says 14mm X11.5 both say 60 degree so does anyone know for sure?

Previous models are using 12mm x 1.5, haven't seen a 14mm to date.

You're in the wrong section for your XE; you want this subforum:

Nobody wants to steal those wheels and any decent thief knows how to take off the wheel locks as fast as a regular lug nut. :)
