Like I said, I don't want to get to heavy into it, because I don't have the best fabrication skills, and I already have a super flexy mini-crawler project, that, due to my lack of fab. skills is benched (whatever became of yours slug?) Here it is:
I would like some more flex out of the suspension, and what I have found is by getting the tires further from the suspension arms, it acts as more travel, because the lever length has increased. I saw the "widening" tip, where you flip the wheels inside out, and that gives quite a bit of clearance. If I upgrade to Overland or similar sizes tires, I will not have to relocate batteries or shave anything. So I am looking at doing it that way. Like I said, this is nothing big, I just want something a little more capable of handling bumps than the x-mod currently dishes out.
