If I remember correctly that guy who had all the plastic interior pieces wrapped in carbon fiber did have Recaro seats however they were not the model cited by Johnnybeas.
That guy had clothlike seats that resembled one of the seats below...

At any rate, any of these seats to include Johnnybeas are super expensive. $1,799 each! I'd like to get either the expert, ergo or orthoped ones but I can't justify the cost at the moment.
