I had an annoying clunk when starting off and when stopping on my ZT190. I changed the droplinks but no improvement. I was under the car last week changing the oil and noticed that the bolts attaching the exhaust collector just below the engine were not there. One broken and one sheared off. I drilled and tapped the broken one and replaced both bolts and the clunk is gone.
Next up, new lower arms to do away with the "pothole clunk".
