I would suspect that if you had a decent ride on the original springs, going back to them would bring improvement. I've heard that there are some aftermarket lowering springs that improve ride comfort, but you would have to accept the moderate drop that they bring. You will just need to weigh the pros and cons of all options. Having owned lowered cars for the past two decades, I've decided that dropping the Z is not high-priority.
I'm fortunate to own a low-mileage older model (2010). I've accepted the fact that the top's mechanics will likely go south in the coming years long before the car hits 100k miles on the clock. When that happens, the car will simply no longer be an all-weather vehicle. As long as I can get the top down and the warning tones silenced, I'll live with it. Not many have the luxury to do the same since their Z is a daily. Your concerns are justified, however. Long live your top!
