Default Does adding ELBJ change Front Roll Center

Spoon feed me, if you will. In what manner does adding Extended Lower Ball Joints change the Front Roll Center, all other items the same.

Or more realistically, if the ride height is unchanged, but the Front (-) Camber is increased (why else put the ELBJ on).

Yes it changes the roll center. Based on the pictures I see comparing them to stock, the pivot point of the ball joint moved up in relation to the ground plane (assuming same a-arm angle) and away from the car center line. This would change the effective a-arm length some slightly.

As for the additional benefits over increased camber adjustment range, the only one I can thing of is slightly wider front track width.

A bit, but not really !!

Yes it would change it "if you didn't adjust camber after installation", however you are moving arm back inboard using the cams negating the change.

If you go from 2* degrees to post 3* degrees, yes small change. If you go from 2 1/2* pre to 2 1/2* post then no "measurable" change, assuming same ride height.
