Wheel offset-measurement

[Ray7]

Hello to everyone,

My Name is Ray and I am coming from Switzerland. I purchased a SRT10 Mod 04 from the US about two months ago and so far I am very happy with my car.
There are a few upgrades I would like to perform. The first one will be the wheels. I would like to upgrade my original Wheels with new 19”/20”es.
According to the swiss law I am able to expand the track measurement by max. 2% per axle.
Therefore I would need the exact offset-measurements of my original wheels?
Please no guessing. I need the exact numbers for the front and the back.
Could anyone help my with this request?

Thank you very much.

Kind regards from Switzerland.
Ray

Who is making the new wheels for you? I think most of the big names have those figures already.

And if the car has wheels on it now, a lug wrench straight edge and tape measure is a non guessing method of an answer.

Are you looking to add the 2%, or just make sure you're within it?

Hello Dave,
I am interested in wheels from 360° Forged or HRE.
To answer your question: I would like to extend the track within 2%.
I`m aware that I could remove the wheels and measure the offset, but I thought someone knows the exact measurements.
