I just moved my extinguisher to a different position. I'm just after comments to see if it is a good place for it or not.
I used to have it behind the passenger seat, but when I got my Sparco Sprint V and harness, I found that I could no longer reach it without undoing my harness (I'm under the impression that CAMS like you to be able to grab your extinguisher without undoing your seatbelt/harness, if this isn't true I might just move it back )
The extinguisher is held onto a 3mm aluminium plate by a M6 screw into a tapped hole with a nut on the other side and a high tensile M8 bolt going through the aluminium into the side mounting point of the seat. The aluminium plate is held on with two M8 high tensile bolts, one of which holds the extinguisher bracket onto the aluminium plate. In short, I think it will take some force to get it to move
Here I can grab the extinguisher without undoing my harness, providing the door is open. I can still access the boot/fuel cap release, again only with the door open lol
So yeah... flame away
