The front geo roll center is most likely below grade.
When you lower most strut suspensions, their roll centers drop something like twice as fast as the ride height. Some geometries are worse in this respect (RC drops more than twice as fast, like what happens at the front on my 626), others maybe not quite as bad.
The whole point being that the magnitude of the roll moment can go up even if the sprung mass CG drops, and the higher spring rate may not be enough higher to fully compensate. A common issue with "lowering springs".
You do get less total lateral load transfer than stock, but you can actually end up with more roll.
