OK we need to start talking "numbers" instead of "worse" or better
I assume you want less positive caster? Moving the adjustments you spoke of in such a way as to move the upper ball forward makes less positive caster.
Which way you want camber? More NEG IE higher number tilting the tire IN means moving the ball "in" so BOTH adjustments need to go in to the center of the car. Since you have the rear one all the way in, is that right? Then moving the front adjuster IN will move the ball BOTH forward AND inward, giving you LESS caster and MORE NEG camber.
I've done this, it ain't my job. It can be VERY frustrating, because sometimes you get into a deal where you have to move both adjusters, and it's difficult to get them tight without moving them the wrong way. Plus, you have to jounce the suspension to re-check. I spent all of a Sat afternoon getting mine aligned. Of course I'm not as agile or strong as I used to be. And I don't have any "special bent tools" LOL to allow easy access.
