Thanks for sharing your expertise, Paul. My dealer claimed that there was only a single, upper adjustment ring on my shocks and NO clicks. He just rotated the top and measured to 1 inch higher ride height. He claimed that there was no lower adjustment. The owners' manual AND the Nitron booklet show – and define – upper and lower adjusters. Could my car have come with the stock shocks? I paid a lot for the DHP! I will "try" looking under the rear for an anti-roll bar later today. I don't have a lift so that won't be so easy. And, I'm 90 years old and have grown wise enough to never again risk fooling with a jack and getting my head under the car. I've been lucky so far. Not going to push my luck now.
