Oh sorry, my bad, but i know the GSR is not the only one with leather. Is it the GS then? I owned a 98 GSR but it had cloth, my friend has either GS, not sure if its leather or cloth though.
Ill probably aim for GSR seats though.

And im pretty sure integra and civic seats are interchangable...when pulling the interior out of my cx today it mounted exactly like my gsr did. Never been in a RSX, so cant have a say on that.
