OEM Stock Mazda Recaro Carbon Kevlar Seats in an FC?
 

A friend of mine recently purchased a set of carbon kevlar seats that were IDENTICAL to the Sprit-R Recaros that are in my FD, the only difference being that they are black (like the older RZ Recaros) and the rails are a bit shorter. I went ahead and examined them and noticed that the part number for them was FC-XXX, so I was curious whether there was an 'RZ' or race version FC maybe in 1992 that included these seats. Are the rails on an FC indeed shorter than those on an FD?
