Yes I think those are for the 350z, would imagine their compatible though as they are the rod ends. As long as the thread diameter/pitch is the same. I was looking into getting tie rods as well, as the other week I was adjusting mine (PITA) and noticed the angle of the rods was crazy. Doubt it will snap, but you never know. For $250 that could be real cheap insurance in case something does go wrong.
