Glad I found this message thread as I'm getting back into autocross and some track day events this season.
I found this excellent video on the Schroth QuickFit harness here:
I reached out to Schroth reps at HMS Motorsports for an update on the status of QuickFit harness for my F22 / 230i xDrive and here's the response:
"Currently there is no quickfit for your car. It is something we are looking into but it will be awhile before we have anything available for it, and that is if it even passes the tests required along with all measurements we must take to safely make a quickfit.

That said, given all the info in posts above, appears one can choose the E82/E92 set and it "fits" albeit not approved for the F22 chassis. As they say...YMMV.
