Follow up question and related. Is it possible to wire up the heating function to the factory heated seat buttons with the 3 settings?

Hey! I'm about to buy a set of Recaro Sportster CS seat and wanted to know if you could answer a few quick questions for me.

1) Are these the right part numbers for the seat for the e46 M3? 411. 10. 1785 and 411. 10. 2785 (Black Leather, Heated)
2) Do all variations of the Sportster CS fit in the e46 M3?
3) These have airbags built in to the side, never seen them on other e46 M3s. Any issues with that?
4) I assume the seats are all standard then mounting brackets are different to fit the e46 M3.

Thanks in advance for the help!
