If it's a coupe, my recommendation would be to DEFINITELY KEEP IT. I have a '92 240SX Coupe (original owner). I have had no rust (which I think is an issue for hatchbacks). A few months ago, I had removed the spoiler to get it painted. It was off of my car for nearly three weeks. Almost immediately I noticed that the rear of car became slightly less firm and planted than before I had removed it. It was especially noticeable driving above 50 mph on curvy roads, which I drive a lot. After it was put back on, the car returned to it's normal, stable behavior.
If I were you, I would keep it on. It definitely has a purpose and works.
