Actually I use the OMP bar. With the 3L intake, it was the only one that fit. And I'm sure it wasn't the strut tower bar.

What I "think" it was:

The downside of the camber/caster kits we have is that I can't have 0 caster, and any camber I desire. When you add negative or positive camber, you end up always removing negative or positive caster. And if you remove negative or positive camber, you end up always adding negative or positive caster. Basically I can't change one without changing the other. When getting the alignment set, I had a choice between dead on camber, or dead on caster. I chose camber, as caster has a much lower effect on overall driving dynamics, and little to no effect on tire wear. Next I got to chose, negative caster, or positive caster. Since positive caster gives a more stable ride in a front wheel drive car, as well as a slight increase in camber on the outside wheels when turning, thus slightly increasing tire contact patch, I chose that.

The problem with positive caster, on a wheel that excercises larger amounts of torque, is the bad angles between how torque excercises the upwards angle forces, versus the angle of strut. Red is torque angle, blue is suspension angle. This may also be the reason why I had so little wheel hop. Using this setup, the wheel doesn't really want to hop, because the suspension will not allow it. The bad news is the result to the upper strut mounts.

The above was my theory... based on how my car was setup, what I experienced in ride, and what the end result to the components were. I may or may not be correct.
