Rims and the meaning of the "ET"

[jamesahawkins]

Just got back into CMS2018 and working on tyres and rims on some rebuilds, I'm now noticing the ET now has a number to it, but only on two rims.
Silly me didnt see it until I was refiting tyres to rims, so dont really know if they came from the front or rear.
What does the ET stand for?
My guess would be for the camber on the front wheels?
Thank you for your help

P.S. thoughly enjoying expert mode :)

Adds a spacer between hub and the wheel.

ET value is german. Einpress Tiefe. With a low value ET the wheel is further from the hub. It widens the wheelbase so the car gets a bit more stability. You can lower the number by using spacers IRL but is not allowed in a lot of countries. In Holland it will not pass the yearly road approval check.
