theres a problem.. when relocating the spray nozzles down that low, they are actually lower to the ground than the tank.. it would work on the j-spec z's because the reservoir is right down there behing the intercooler, but on a-spec, when the tank is in the back, it wont work. the water will continually sump down through the nozzles after your done spraying.. ive tried all kinds of check valves, and nothing works. not even the stock one that was mounted to the stock windshield nozzles.. but i do like the idea of the button.. you could use it for nitrous or something..
