Unfortunately it's not tyre related. Additionally all 4 wheels / tyres were rebalanced by the workshop. If i press the clutch and the rpms fall down, the vibrations go away immediately. Definitely engine related.

Yes, i've considered that. But in my little world a resonance would only happen in a very specific rpm range – let's say a range of 500 rpms. But in my case the vibrations start at 1.500 rpms, are really present from around 2.000 to above 4.000 rpms and than disappear above 4.500 rpms. Also it is possible that i can't feel them below 1.500 and above 4.500 rpms.
In my understanding a resonance would only happen in a very defined rpm range, like the exhaust resonance in these cars, which are always around 2.800-3.000 rpms.
And even if there are more than 2 components that resonate with each other, the rpm / vibration range shouldn't be that big and evenly.
I'm still not understanding what is going on there and why the workshop didn't focus on eleminating the definitely engine related vibrations in the footwell.
