I just bought a base 350z and id like to add 19" wheels But, how is the spedo going to be adjusted When i had a crustang all i had to do was change a gear in the spedo cable. What do they do with the Z?

 

If you run 275/35 or 285/35 in the rear you shouldn't have to calibrate at all. You'll be off, but only like one mph in either direction.

 

Maybe you'll get lucky, like I did with my Acura TL I used to own, and the Navi will be more accurate! LOL Assuming you have one.

 

Sorry, no nav its a base model with 17' wheels

 

Well, I noticed that my speedo reads about 4% LOWER than what I am really going. I am hoping to get some tires that are a little smaller (245-40-18) and hope that will correct it a little bit....that way I will be about 1% high or more or less right on....

I also heard that the sensor might be in the front wheels, so my thought is out if that is the case.
