yes, because i did the opposite of what you are asking. you will need to swap airbags, passenger sensor, etc. from your old seats and the 2013 ones. you can read in detail how from the other thread you posted in for recaros.
I've read that they changed the air bag sensor/connections (under the seat) in mid 12'.. Late 2012 should be fine. It seems that the issue is the side air bag connections which were changed. People have went around that using different resistors etc..but haven't seen anything that's 100%. To keep airbag light off.
