i put gsr seats in my rex, i also had delsol seats in my rex, the sol seats sit extra low, but the integra seats are a little higher, but feel nice. anyways, only 1 of the 4 mounting points on seats fit, so i had to make some custom shit to fix it. if you have the stock crx seats, just swap out the rails. thers a tutorial somewhere online, but i forgot where. anyways swap the rails, or do what i did. i didnt have the rails, so i bought some rectangular steel shit, ti was like 2inches wide and like couple feet long. i then basically bolted that into the stock bolt points on the body, and then bolted the seats into the steel. fits good.
