Well, I drive a 98 gt vert (auto *tear) with a 4 point rollbar in the back. I am going to take my backseat out, but I dont really feel like dropping 150 on a rear seat delete. I am planning on making my own within the next few weeks, but I am unsure on what material I should use. I need something that doesnt weight a lot, but is durable, because my trunk is kinda, well, "in use," (one 12", 2 amps, 1 cap) and I will be using the backseat as my mini trunk. If anyone has any ideas on what materials to use, let me know, thanks a bunch.
