Is the 2003 lug nut pattern different then others? I bought 12x1.25 cause I read that is what our cars use. So I sold my old set, and bought the said bolt pattern. Well now these don't fit. I guess I should have checked the old ones to see.. but can anyone solve the mystery?

Nope, been the same on all 350Zs. Are you the original owner? If not, is it possible the previous owner replaced studs (can't imagine why someone would change size/pitch though)?

Odd, I should be able to take a lug off and check it at advance or auto zone right? I'm with u #3 why would someone change all 20 studs

Did you take the dummy post off the front?

Maybe because that's all they had available in the right length. Either way, kinda foolish.

You can buy a thread pitch gauge to check the TPI (threads per inch). You're confusing the term with "lug nut pattern" with "thread pitch." You're bolt pattern (lug nut pattern) aka PCD is 5x114.3mm. What you're trying to figure out is your lug nut specs, which include diameter and thread pitch.

I thank you guys for the help, buahhh you ready for this.... The on stud I tried it on, out of all 20, was jacked up, I'm sorry for the inconvenience. It is 12x1.25

Ya mean you didn't suspect it was cross threaded and trashed??
