Hotchkis TVS Stage 1 Kit experiences
I haven't had any bad experiences with my Kit. I've set my sway bars to the third setting and it's great. This kit with my 20's made a hugh diffence. I looked at a few different alternative but for the money you most certainly cannot go wrong.
Make sure you get a four wheel alignment.
Enjoy......

The rear springs are softer but the Hotchkis sways, that come with the TVS kit, stiffen up roll resistance. Without the sways, the perception of less body roll may come from having a lower center of gravity.

The poster said that he ONLY had the springs, no swaybars. From what I have read about suspension geometry, it's not the center of gravity that has the greatest impact on body roll, but rather the roll center which is not usually the same point. On top of that, the center of gravity and roll center don't usually change at the same rate as you lower a car.
I could be wrong on this next statement, but it seems to make sense. When you lower the car, the CG will always be lower. But, it seems like the roll center is also improved after lowering the car making it roll less than stock given equal spring rates.
Maybe somebody else has better information to work with, but I've searched all over these forums and the internet and this is what I've come up with.

From what I've been reading online, when you lower a car it messes with the center of gravity and the roll center of the car so that you USUALLY get more roll and more nose dive because now the geometry is out of whack. Sounds like you are observing the opposite.
Thanks for the observation, helps a lot. I've been obsessing for months over how lowering the Z affects the overall suspension geometry.

Wheels are 19" w/ 255/35 in front and 285/35 rear.

I'm on the fence with this kit. I liked the mild drop for city driving/clearance and the fact that you can get back into alignment spec without having to buy aftermarket control arms. I was also attracted to the "claimed" lower drop in the rear b/c the Z does ride a little high in the back and of course the price.
My kit didn't drop the advertised amount so they sent me a second set of rear springs which dropped about the same as the front but still not the claimed amount for whatever reason.
I was concerned with the low spring rate in the rear as well but really only notice it when I go over one bridge in the area that has seams...then it bounces, which is exactly how the 2003-2004 guys described the 1st gen soft suspension (mine had the revised 04.5 stiffer rear springs).
With all the amazing reviews on this forum I guess my expectations were set too high going in. Yeah it handles better at lower speeds but high speeds are a bit less confidence inspiring. Perhaps with better matched shocks that would change?
Oh and I have the swaybar clunk front and rear going over odd-cambers too...planning on getting under there soon to check that out, but the solution seems to be a new set of endlinks.

Did you cut the rear spring mount? I realize you have 19s and i got 18s, but still it should make that big of a difference... should it?
Another with the NTO3s

Use "locktite" on the end link nuts are tighten them as tight as you can get them without striping the bolts/nuts...that will fix the clunking noise

Yooo can you please post pics of your rear tires... rear shots, width and so on.
Thanks,

You can see some WIDTH in this pic... They're preeeetty wide:

thanks though!
