So, for anyone interested ive done some digging, and with the assistance of a mate whos quite into his VR and Sim stuff managed to get one working and its surprisingly good.

https://www.patreon.com/posts/preview-bmw-z4-66443479 This is the pateron page for the guy who made it
https://drive.google.com/file/d/14e9_sI1GSoQ2vOoiTfoiR3JZeUATCW_H/view?usp=sharing and this is the direct download.
You need to grab content manager from here: https://acstuff.ru/app/
Then go to the menu and install from a file and click the downloaded zip file
Then select the car from the list (bmw z4 roof) and do "analyze"
Then you can go to the drive tab, and kick off a driving session and it works great.
Note: You will need to tweak the camera position as the default in-car camera locations are a bit low. Move the mouse to the right-hand menu when in drive mode. Click "onboard settings", and move the camera to your desired location. Then click all the save options.
But, the most hilarious part... the iDrive completely works

(all be it an older version of iDrive)
Wave your mouse over it and you can click to enable sat nav, open the radio, backup camera, spotify even controls your windows media and starts playing whatever is in your playlist, even the Youtube app lets you search youtube in real time. I am absolutely gob smacked by the level of detail here, its mad.
So yeah, takes a minute to get it working, and i think the tire grip / downforce settings still need tweaking to be accurate (it seems to let go sooner than i would expect at a given cornering speed), it would be nice if they did it in RHD instead, and it seems the speedo is hard coded for KMH (even if the game is running in MPH), but you cant have everything.
