Rockers / Side Skirts Question

[FRZ951]

Hi !! Each of my 944 have this rockers.. I would know what is the name of those rockers, if they were in option list while bought the 944 in 1988 and where they sell it because on google I found NOTHING!

As you can see, this is not only the "boxed" rockers but on the rear wing there is kind of lines


If thats not enough clear, I can take a picture of them removed. Because I probably will sell them or keep them I dont even know. For now they are removed because they hide the "wideness / curves" of the rear wing when viewed from front of the car. see the other picture.



Thanks!
