Moving the top of the MacPherson strut rearward will cause which change?

In a MacPherson setup, the caster angle is set by the orientation of the steering axis, the line through the upper strut mount and the lower ball joint. Moving the top of the strut rearward tilts that axis so the top sits further back than the bottom, increasing positive caster. Positive caster improves straight-line stability and steering self-centering, though it can make steering feel heavier. The other options aren’t primarily affected by this change: camber is the wheel’s tilt in the vertical plane, toe is the horizontal alignment of the wheels, and ride height is about vertical vehicle position—none change mainly from moving the top mount rearward.
