I think you are a little mixed up on weight transfer, it seems backwards to me.
Also front strut bars do little to nothing on this car as the strut towers are right next to the firewall. The rear one does a lot more than the front.
I have noticed a pretty big increase in torsional rigidity after having these installed. Chassis flex seems non-existant now. Even if you think its fine before, after having these you will realize how much your car flexed before.
