For those with fire systems, how/where do you have your bottle installed. In my brothers RX8 the bottle is attached to the cage in the passenger side. Specificaly on a horizontal cross bar that runs along the rear floor where the front of the rear seat cushion would mount. My car does not have this bar. The only cage option with keeping it near the floor is vertical on the b pillar or at a ~45 degree angle on the bar going to the rear the one running across to the drivers side. I cannot mount it on the unibody where my brothers cage/cross bar is because my cage gets in the way.The floor seems like a good option but when mounted sideways (recommended direction) it takes up the entire space from rocker to the transmission tunnel, not sure if that is safe in a side impact... Thoughts?Last question, if you mount it to the cage what mount do you use and where did you get it?Thanks for the help;Raymond
