On the other hand, I found a brand new M3 rack for 600€ (680usd), and am willing to give it a shot, I wouldn't mind a firmer steering wheel.

It just remains to decode the AS so that it doesn't give faults, and eventually somehow retrofit the Servotronic, some e87 guys did it, but no one gave exact instructions, I guess I'll have to explore and discover for myself.
I haven't done this yet but have done the coding for others and it's certainly in the queue. You should be able to just remove AS from your VO and add Servotronic, default coding it all afterwards. Servotronic itself is wired in the JBBF, where you should also check to make sure it is coded aktiv. There's also a cutoff point in JBBF modules that support this, you'll need to be JBBFEII.C06 or higher.

Here's a link to the wiring schematic. https://www.newtis.info/tisv2/a/en/e...tronic/v6RC5hy
