Wheel Offset Calculator

This wheel offset calculator shows the effect of changing your wheel width and offset on your 350Z, GT-R and 370Z

How to use the offset calculator

1. Either click on your current wheel or enter your current wheel width and offset*

2. Enter your new wheel width and offset

3. Click the calculate button

The calculator will then show the clearance between the inside of the wheel and the strut housing. It will also show how far the outside of the wheel edge will extend or retract.

If you reduce the inner clearance too much or push the wheel out too far, the tyre might rub or not fit at all.

This calculator is for information purposes only and nissansportz do not guarantee fitment based on this calculator alone.

*Be sure you are in the correct section for front or rear wheels as the built-in Nissan wheel dimensions differ from front to back.
