Hi Armando, I send you some pictures to hopefully answer your questions:
This picture shows the racing seat bucket you are now looking for (co-pilot) and the seat is upholstered. It is the same seat I offered you earlier. You see, if the seat is upholstered, you can not see the provision for the headrest. If you upholster it in the Black Nomex material like the RSR race-version (this photo shows the leatherette/corduroy for street-version) and you dont make holes in the Nomex material for the headrest, it will look the same as the RSR and that is exactly what Recaro provided Porsche for the 911 RSR...
