SuperPro Roll Control ball joints for more camber and raised roll center

you don't really need to compensate with spring rate. you want the roll center and center of gravity as close as possible and as low as possible to reduce how much the car sways. it'll make your sway bars more effective if anything but i wouldn't mess with spring rate.

and the alk can raise your roll center too. you just need to rotate the bushing appropriately.

The problem is you're modifying the wheel rate at one end of the car and not the other. The other problem is that you're doing it via a means which is very difficult to measure and requires seat-of-the-pants experimenting to determine if the change was positive or negative.

If you install both of these without knowing how much of an effect one has versus the other you have no idea of knowing how you're adjusting the balance towards understeer or oversteer.

Regarding spring rate adjustments.... unless there's a way that you know of that can adjust the roll center at the rear of the car, the only option you have for correcting balance issues after installing these parts is to adjust the spring rate via springs or swaybars.

Body roll is not an inherently bad thing. As long as you're not hitting the bumpstops and sending the spring rate to infinite your car has as much grip on a perfectly smooth surface as a car equipped with the same exact tires that has zero body roll. I can appreciate the personal preference of wanting as little roll as possible, but you have to understand that the compromise you're making is loss of grip over surface irregularities. With no suspension compliance if your tire cannot absorb the impact it bounces and loses contact with the surface, which is as undesirable as bottoming out because the suspension is too soft for the tires you have equipped.
