Ozwald.
The purpose for this is to make the car rotate on high bite traction tracks and not tip over or pick up tires.. By lower the hinge pins it makes the car much looser but not with more steering just less rear grip.. Where as running the camber link down and long makes the car rotate like a SOB. I did put .030 shims under my shock tower i forgot to mention.
Hope this helps.
