So now we know that 1/8 inch flat aluminum isn't enough to support bumpers. It would seem difficult for the GDC to make that decision without knowing a few more things about the setup in question. How far does it span between other support, how wide is it?
We have been building a west coast style frame with 2 standoffs between each wheel leaving about 7 inches between each. I'm not sure what to do with it now. Is 3/16 plate between them enough to satisfy the rule?
