In germany we need to show every mod to a technical car agency before we can drive with it on the streets legally.
So I just installed some spacers on my G.20mm in Front an 25mm in the Back with my OEM 19" rims.It looks perfect to me ,theres no rubbing.
Now I wanted to check them by the car agency but the inspection authority need a certificate from Infiniti or Nissan wich confirmed the maximum axle stability.
So I have now an effective offset of 10 in the front and a offset of 8 in the back with my spacers installed.
Can someone help me out with some papers that proof the axle stability due to my offsets.

 

Good luck with that. I don't know if any state in the US needs certification like it (CA doesn't). Really, it's not as much the axle strength as the strength of the wheel studs and/or bearings when you add spacers. I don't want to get you into trouble, but can you just remove the spacers to get inspected?

Oh, and props for trying to do it the right way.

 

thanks for your answer.the problem in germany is that I need to inspect the spacers not the whole car at the moment.So if I dont do that and the police stops me to control my car and the see the spacers which are not controlled (with no papers) they will give me a fine of about 300dollars and the can shut my car in the worst case.
Ive just found H&R Papers for 350Z Spacers they proove the stability of the axle till a offset of +-0.So I only need some papers wich say that the G35 has the same axles as the 350Z.Maybe someone can help me out with that.

 

keep us updated...

 

did you try emailing HR tech support for thsese docs?
