If the surface is loose/dusty, maybe double dees, ifmar pins, maybe 3ds. look at what the fast guys are running in 2wd as well. I would bet 95% of the problem you are having is tires and the diff.
Hey thanks for the reply! I think the pins are a little big on Calibers for the 2wd buggy so your probably right but had decent luck on my SC10 FT with them. The buggy was ran and built by Zach Genova who is a good guy to deal with anyway the diff was pretty smooth but really easy to rotate wheels opposite like 1000wt diff oil almost so I tighten it about a 1/4 turn still felt smooth but tighter which all setups I see say tight diff. I ran it for a pack then checked it again and it was a good bit lumpy feeling so I backed it off like it was and better again so I will leave it like that until my rebuild stuff comes. I am getting some DD's soon and thanks for you help!
