Why? I see no physical reason for that to be true... Why would the rake angle of the body make any difference at all? It seems like the weight transfer would be determined by the height of the cg above the axles. It wouldn't make any difference at all if the body was vertical if the cg height was the same. I'm still puzzled... Lowering the rear would lower the cg, and reduce weight transfer to the front, but lowering the front would accomplish the same thing.
