Good evening. After having a friend go through an almost fire scare with his car a few months ago and a few conversations with a few others about race car fires, I'm curious what others are doing/using for fire suppression in their race cars. Seeing what a friend installed, has me seriously considering a system like his, that covers engine bay and drivers compartment. What manufacturers/systems do y'all use and like. Cost, installation and other factors as well. Big tire door car specific. Thanks.
