The are an option on the MK6, which is what he's referring to.
I would find a car with the seats already if you can! They're very expensive second hand and I hardly see them come up for sale (MK6 Recaros).
I have standard R32 seats in my R32 and upgraded them to the full leather MK5 Recaros (same as MK6 without the suede) and they were far better! But I do have a large back.. I sold them separately when trading in my R32 for my R and the ride to the dealer in the standard seats was not fun!
