I will make some assumptions here.
You are running a 3 link versus a 4 link stock set up?
The advantage is that with the three link you are creating greater anti-squat which in turn gives you greater forward bite. the other huge advantage is you use a panhard bar which not only locates the rear end side to side in the car but you can also adjust your rear roll center by raising and lowering the panhard bar. That is one of the greatest handling tools to work with.
not sure if that helps?
