Well, I had them installed yesterday...and my God are these springs amazing. They are super smooth - even over bumps and such. I was absolutely amazed at how there seems to be virtually no difference in harshness...hell, I'd go as far as to say that the car actually feels better than stock (and I'm not talking about how it handles).

Everything feels so silky, especially driving. The first thing I noticed about this suspension is how it makes the car feel like it's gliding, as opposed to driving. It almost has this...dare I say it...BMW-like quality to it, where the ride is just so smooth. The car simply feels more fun to drive, more engaging.

There is a noticeable improvement in handling, body roll is reduced considerably. What else can I really say besides that? I did a few tests with a few of my favorite places, and the end result of this install is totally worth it.

Where as when I had a 5th gen Maxima, installing springs would make the ride quality too harsh no matter what springs you chose -- these Hotchkis improve the Z in nearly every respect. The springs aren't "tolerable" or anything -- calling them that would be a slight against them.

They feel pretty much identical to stock, with noticeably better highway cruising, and notably reduced body roll. The only drawback, of course, is the increased chance of scraping the lip. Regardless, for just over $100, this should be that one mod all Zs should have.
