Few things:

Looks like a lot of stress to put on 2 "rails"... Have you checked to see how this set up will take the stress (seems like thin material to be using)

Also as for cantilevered wheels: i wouldn't do this. First off if they aren't very well protected it is easy to play defense on you (i.e. stopping you from driving around)

Also why not use all 6 traction wheels with the centered one lowered (similar to the kit chassis) as this will make sure you have full surface contact and will make it harder for a team to "spin" you around.
