See? There you go again...the tighter a diff is, the less it functions properly. In 17.5 which I presume is what you race, the diff should
ONLY be tight enough to not bark period. A properly working diff works right along side with the sipper...not too loose, and certainly not too tight. It will allow the car to jump, accelerate and corner the was it is
supposed to!
