No, I do have them dialed down a ways, but I find them suitable. I think if I were running heavier batteries or electronics (or street running) maybe I'd want heavier springs? As for the diffs, I run them a bit on the looser side. I prefer control over forward drive. Too stiff a fluid forces the wheels to break loose easier on turns for me. I'm not really a "basher" by traditional means I guess.I think i'd like to try 15/20/10 for diff fluids. One of these days i'll get around to adding a few more dabs of 30k in each diff to stiffen them up. TBH though, tearing diffs apart is probably my LEAST favorite thing to do... so it will probably be a while.
Bunch of people complained about how soft the SCT rear springs were. I haven't really gone off road, so i can't comment. Any complaints from your end?
