You will not want toe out, toe out will make the vehicle really unstable at speed lots of left and right moments with terrain change. Keeping the allignment at 0 will give you really good highs peed cornering but still be a lil unstable. Toe in will give the vehicle a smoother steering feel as well as it will iliminate the unstable steering feel and track better down the trail. Rule of thumb is usually around 1/4 to 3/8 toe in . I like to set it at 1/4 with no weight I'm machine
