You need to refine your question IMO. As a test, add 40-50 lbs on the front of your car, make sure it can settle from the extra weight, measure that amount of movement, now in your comparison test if you make no other changes, the question then becomes, do you notice the difference in weight AND the additional ride height with the correlated alignment changes, albeit small, but still a factor?
Regardless, its nearly the same as 9 gals of fuel, which is about the lower driver limit for I would say the better then average on this forum.
