For water. For gasoline it's even less, only about .34psi.
BB just texted me and said I wouldn’t be pulling that many G’s....that hurts

Is there any reason why we can’t go to an aluminum spacer in our rear wheel? This weighs a 1/2 lbs.
No. As in there is no reason not to. Double bloody negatives....
If you have a lathe and raw material it's a good idea. Add a couple of thou to the legth to allow for greater crush on an aluminum tube, and flange the ends to say 4mm larger diameter for say 3mm to allow it to center properly and you should be good to go. It doesn't need to be high strength or anodized. Use easy machining grade AL.
Or cross drill the steel spacer. You won't save as much weight and it's hard to deburr the inside of the holes, but it's cheap.
You can also cross drill the rear disk. I don't mean those tiny little gas reducing little holes. Cross drill with say 25mm holes on a mill. Rear brakes don't do much. Think of it as an emergency brake and as long as it's as good as putting your feet down, you are good. OK so that was a little tongue in cheek, but you don't need a lot of metal in a rear disk to be operational.
Add lightness.
Drill out the stakes on any (Honda uses them, too) retainer before removing. A new retainer can be ordered, but screwed-up wheel internal threads take a lot of work to correct.
