Yep, I'm opinionated! 45 years in the trade will sort of do that to a guy! I'll agree that lowered spindles are the least dangerous way to lower one, but even then, the "scrub radius", (the imaginary line through the ball joints that intersects the tread centerline) gets out of shape. Oddball tire wear is the usual result, plus some pretty unpredictable handling characteristics in an unexpected shap turn. Once a suspension system starts operating at the upper, or lower limit of its travel, all sorts of things start happening to roll center, roll couple, center of gravity, etc. "Ackerman", generally called "toe-out in turns", can also be affected. As long as the vehicle is driven only in a straight line, at low speed, we can play all the ride height games we like.
