In that case I would say the center shock was controlling the weight transfer forward and the damper tubes left to right. So the 2 working in concert would increase the weight transfer to the front outside wheel.
Oddly enough we've found at our track that increasing the lube in the tubes has actually increased grip. Many of us at our outdoor track are running 30k oil in the tubes, lighter than that and the car actually gets loose. Down around 10k lube we start to see the inside rear tire lift.
