The upgraded recaros that didnt make it to the US (pictured) were the ones that you couldn't adjust. The Recaros that we get here in the US are adjustable, and with the RS2 package are actually electric adjust.Just found a copy of the Focus RS Owner's Manual online.
Not sure what they meant bu supplement but thought I'd share it.
Apparently you can change the seat position? Thought they were stuck as is.
A Lift the handle to move the seat backward and forward.
B Repeatedly lift the lever up to raise the seat.
Repeatedly push the lever down to lower the seat.
C Rotate the handle or move the lever to recline the seatback.
Cheers for the Owner manual!
