[nurburgring]

As the title says it, i need to know the production numbers of the most popular steering wheels sold worldwild.

I found nothing on the internet.

I currently think about adapting my revolutionnary cockpit for the T500rs too, or only for DFGT and G27.

Thanks for your help.

If it is not available directly as unit sales figures, you can derive it from the financials over time.
