For ages I have been looking for a way of storing tools, tyreweld, compressor, scissor jack, spare throttle cables, etc. in the FW boot so the collection of seemingly random items I carry don't slosh around.... I also wanted the ability to easily take things out when I'm at trackdays.
After a few pointless purchases that didn't do the job, I stumbled across some cheap bags when buying some DIY stuff from my local Toolstation.
Thankfully in real life they are actually black rather then green!
The 450mm slots in nicely (if you don't have it too full) in the smaller lower portion of the boot, and the 750mm sits above it below the lid. You could probably use two 750's if you felt really flush and wanted to spend the extra two hundred pence.
The 750mm even accommodated the large PX600 airbox I used for trackday noise reduction.
They aren't the last word in quality, but its a "first world problem" solved for just 12 quid! My Scottish genes are very satisfied 😂
