Ok well I finally got an enduro car, thanks to Charlie's towing. Anyway, it's a 4 cyl Sentra and I have a few questions.

Since I can't use antifreeze, what else do I use? I've heard about water wetter, but where do I get it and how much will it run me? Are we allowed to keep the speakers on the rear deck of the car or no?

Also, how much do firesuits run, about, and anyone know where I can buy a cheap used one?
