I would hate to see you guys with diff/slipper dyslexia problems running a 4wd model that uses ball diffs
. I had umpteen B44 models before my XB4s, and if you over-tightened that slipper even a little, you'd shred a ball diff within the first 3 hot laps, especially when you land a jump on power. I run on a high bite clay track where we use slicks in the winter as well. I agree that high bite wears on a drive-train twice as fast as loose. I know when we run mod 2wd buggy, I'm rebuilding my ball diff once per month. Despite this, I still have yet to destroy my XB4 gears after a full season of racing every weekend.
