how heavy are standard fd front seats ?

[michaelb]

Hi All
Does anyone know how heavy are standard fd front seats?
Also, do new standard stock RX7 seats still exist if I wanted to buy them?  How much is the driver’s one?
At the moment I am thinking of getting the below seats but I don’t really want the new seats to weigh more then the standard fd seats..
