RE: weight transfer - vehicles always transfer weight in dynamic motion. Putting heavier or lighter springs in does not change that. What heavier springs do allow is to lower the ride height without suffering the same bottoming of the suspension during this weight transfer. This lowering allows us to alter some of the geometry that helps reduces dynamic weight transfer through the roll centers. It also keeps suspension travel in a narrower range to minimize dynamic suspension changes that less than ideal component geometry can introduce.
