Roll Center Adjusters

[Rosebud]

Has anyone had any experience with roll center adjusters? [https://stevestonmotorco.com/collections/hardware/products/fletcher-roll-center-adjusters] They're recommended for lowered cars, and mine's pretty low. The racers say that the outer ends of the lower arms should be higher than the inner ends. Mine are pretty much parallel to the ground as the car sits. Of course, when cornering the outer ends move higher, so it sounds like I'm a candidate for the adjusters. A fellow on another forum said that ideally, the upper arms should be lowered as well. The problem is that there's no way to adjust the upper ends without some serious fabrication work.

My question is: What are the consequences of installing the lower arm adjusters and not do anything about the upper arms? It looks to me like positive camber would increase during cornering, which may not be such a bad thing. Anyone have any thoughts on the matter?
