To give you some idea of how stupidly overpriced these seats are from Nissan:

$5K USD for seat back alone.
On ebay, they go for $2-3K a pair, subject to availability and shipping

Unless you are dead set on OEM Recaros, I would strongly suggest looking at Recaro Sportster, the seats that Nissan borrowed from
I assume you have relatively easy access to a Recaro dealer in your region
