One Lap of America requires a fire extinguisher to be mounted in the car. Not to mention, cool points with the scene kids.
I already had a 2.5lb halotron bottle and bracket but couldn't find a good way to mount it. It turns out that euro E39s had a little bottle available as an accessory that mounted to the front of the seat. If you don't mind buying from overseas ebay sellers, you can still find the bracket but the bottles are impossible to find.
Fortunately, forum member Bleedsblue made a bracket that utilizes the existing holes in the seat frame and provides for mounting of the standard bracket that comes with pretty much all 2.5lb bottles.
He actually designed it for the E34 (the thread in the E34 board is here: https://www.m5board.com/vbulletin/e34...e+extinguisher
) and sort of discovered it fits the E39 by accident.
I ordered through his website and was able to install it on the passenger side in about 20 minutes. I opted for the nuts/bolts version and not the rivets. It's hard to get a wrench on the nuts but doable. On the E39, the mounting bolts are a bit too long but I informed Bleedsblue so I'd expect any future E39 orders will come with slightly shorter bolts. Only downsides of the passenger side mounting (apparently Bleedsblue didn't experience this mounting on the driver side of his test E39) was that the bottle only fits in one orientation, which is nozzle outboard, with the bracket bolted down to the inboard set of mounting holes. Otherwise the nozzle or handle hits the seat or seat shroud.
We did some autocross runs after the install and the bottle didn't make any noise at all, which is great. Additionally, it's within easy reach of the driver and yet is visually unobtrusive.
Definitely give Bleedsblue aka Angry *** Solutions the thumbs up on this one and recommend it if you want to mount a bottle (let's be honest...with the age our cars are, everyone should have one). I also recommend springing for the halotron so you can avoid the dry chemical corrosive aftermath. I already had the 2.5lb bottle and it does indeed fit but the smaller bottle (1lb I think it is?) would probably be a really clean fit. But hey I've got 2.5lbs if I need it!
