Forward traction and side bite are different things. the shorter link will increase side bite and cause it to push off power, but will reduce forward traction. If the rear doesn't have as much forward traction/grip then it will increase the amount of steering you have on power. Hope that makes sense. Try it for a couple of laps. Doing this one change made me understand the difference between side bite and forward traction. I never really fully understood before I felt it on track.
