I am getting redy to mess with the trail only rig. I am looking at building alot of flex for cheap, and use as many parts as I can. I was looking at doing this (see picture) front and rear. Seems like this would work for flex but not sure how strong it would be. I am sure its not an ideal way to do it but I am cheap, and the vehicle is going to be a trail only vehicle that probably wont ever see anythng about 30mph.
