I'd like to use something more solid than the floor, even if it meant making a dedicated shelf like in the R33 mounted on two hard points.
I can understand why race cars have boxes mandated, and why it makes sense to have a vent. But the R33 has no box and therefore no vent, or an infinite one depending how you look at it. Mounting aside, I guess I have to talk to the nice people at the NSW RTA about the requirements for a streeter.
