Ok, so I should go for 0* camber. But I'm still confused on the effect of adding or removing shims. If I remove a shim, then the UCA shaft is closer to the frame, and the ball joint is farther out from the frame. Then the top of the knuckle is out farther, tilting the wheel out at the top, increasing camber. So the rule is remove shims to increase camber, and add shims to decrease camber. Do I have that right?
