I'm thinking about going to a local track day!! I'll be bringing a 95 RS250. The previous owner had it prepped already with safety wires and the bit. I just need to make sure everything is bolted down and to remove the mirrors and cover the lights. Now I was also told by someone that I am not allowed to have antifreeze in the radiator fluid. If this is the case, I assume I'm using just straight water. Is this so...any other precautions or prep work that I need to do?
