Hi Folks,
For what its worth... I have fitted Recaro SPG seats to my car - the thread is still here but I got 'photobucketed' like half of the internet did so pics are blocked...
Here's the thread: https://z4-forum.com/forum/viewtopic.php?f=9&t=77724&start=30
From memory - I used VAC floor mounts (these are excellent), Recaro side mounts (steel as these are lower) and I welded an M10 boss to one side so that I could mount the standard pretensioner seat belt buckle - just plug that into the seat loom. For the passenger occupancy airbag sensor, I searched a generic online bidding site beginning with 'E' for an emulator and connected this to the right pins on the passenger side plug (again an online search helps here). Coding this out I believe is tricky but not impossible - BMW Coders were unwilling to commit to help as they saw it as a safety issue to actively disable an airbag (understandable). The only downside of the plug-in gizmo I have is that when driving alone I have buckle the passenger seat belt or the car shouts at me as it thinks there is someone in the passenger seat.
The seat is plenty low enough set up like this (in fact much better than the standard M seats - apologies to the purists!) with enough head room for me and my helmet for track days (I'm 1m 75 tall). The only issue is seat width, with the door panel fouling the seat slightly - that might be worse with Pole positions? I've stuck small high density foam patches to minimise damage to the seat and the door panel.
Overall, a bit of a pain in the backside, but well worth the effort - took me a day end to end.
Hope that helps!!
