Havnt installed them in my falcon but did have aftermarket seats in my GTR, had a genuine recaro for the drivers seat and a replica for the passenger... ( I bought the car this way) tbh from a visual perspective was hard to tell difference unless you looked really closely but me being anal I wanted to swap it out, much heavier then a genuine recaro and the padding material was no where near as good...... recaro make a great seat though
also if you do go the aftermarket sport seat route check dimensions carefully some recaros (and other aftermarket seats) are a super tight fit, I was really fit during the time I owned the GTR and I always struggled with the leg bolsters now 20kgs heavier I don't think I'd fit in to them hahaha
