for whatever it's worth regarding the inner tubes, i think the factory purchases the wheels and tires as a set that come to the factory pre mounted therefore short of a car getting a flat during the build process there's not a huge need/demand for the tubes. most tube requests are probably filled directly by the dealer by them buying them direct from the mfg. not making excuses, just thought i'd throw that out there.
hope you get your other bits and the suplex setup sorted. i chicken out on my order and specced the spax setup as i got scared seeing some of the reports on the suplex but will admit i've always lusted after how they look as well as in theory how they should perform.
