So with the new updates to the MSNZ manual all fire extinguishers now require two quick release straps.
If theres enough people interested ill sort a group buy and save us all some $$ , iirc they are $59 normally ( at Japrace )
The best price I can do on these is $29
Although im sure there are cheaper ones available , these are Flame Guard by Chubb , they are good quality and have a decent mounting bracket and straps.
They are also the model that MSNZ reccomend.
Even if your not into racing its cheap insurance against your car burning to the ground should something go wrong.
