When I made the mistake of running 2" drop spindles on my Challenger that was when I actually noticed things weren't right. Doing some "spirited" driving/cornering on winding mountain roads. Under more standard street conditions it wasn't noticeable. When I was able to plug some geometry numbers into a program it was pretty clear that the 2" drop spindles increase bump steer noticeably compared to lowered the same with the stock spindles, and that was the unsettling feeling I was getting when I was pushing the car a bit harder into the corners.
