Thanks for the clarification, although I'm not sure I'm 100% clear still.

In this case wouldn't lateral (side-to-side) movement and horizontal movement be the same thing? Anyway, some real world impressions would be great. Empirical, objective numbers reflecting a performance improvement of some type would be even better. I understand what you're saying but until I see some real numbers I'm still of the opinion that Nissan put these things there for NVH reasons. Sure, they'll add on an, "Oh yeah, they help with high speed stability too" statement simply because the Nismo Z is supposed to be their pure performance model. But, unfortunately for them, I'm not the type to just swallow (and ask for seconds) all the marketing BS that corporation xyz tries to shovel out there without proof.

I'll tell you off the bat there is no need to give any sort of #'s - I neither have the equipment, nor the time, nor the location. But, good or bad, I'll tell you all about it!

Thanks for your efforts. And FWIW, please don't take my questions as questioning YOU. I'm not. Ever since I saw people start talking about these, I've been curious (yet skeptical obviously), and hoping for a real explanation. I appreciate your efforts.

will this fit intercool'd turbo/sc'd cars?

Cheston - I doubt it based oon where it sits

It seems that the problem is a lack of chassis rigidity leading to some unpredictable handling.

These look like the equivalent of strut bars with a shock absorber in the middle.

I suspect these dampers increase rigidity of the chassis in a controlled way so as not affect ride or noise transmission to the passenger.

If one wanted maximum rigidity, why not simply install solid bars instead of the dampers? It would perhaps even be cheaper.

They could be simply made up using tubing, rod or clevis ends using the Nismo mounts alone.

having now had mine in for 3 days, I will keep this brief. I'm doing some notes so I can prepare a full review on them. Ride quality has IMPROVED....dramatically, especially over uneven pavement. My car is quite low, coilovers, 19's, etc. While the car was certainly liveable for everyday use where I live, this has taken it to a whole new level! 40mph over ruts in the road are significantly better absorbed than they were before - you no longer have one wheel "hopping" over it as was the case in the past...it literally softened the whole ride up front in these conditions, and it's amazing. The more I've researched these types of braces, which Yamaha has done for several companies now, the more I am discovering they are used on factory cars that have non-traditional suspensions (ie stiffer than the normal suspensions - such as the Spec C STi, the 380RS, etc). So my best educated guess is they are using these dampers to bring back some of the independance that is lost when you start with more aggressive valving, stiffer rates, stiffer sidewall tires, etc. On smoother flat roads, I have not played much as I've been datalogging some things for an upcoming project, but turn in response is definitely quicker than it was before the damper. Stay tuned for a full review coming soon once time permits and I've put some more miles on it. Again, I only installed the front, as my sub box prevents me from being able to fit the rear.

^ I agree Z1. If you get a chance drive a Nismo Z. They know what their doing. Don't forget the Nismo Z's chassis has extra seam welding done as well. I think the dampers allow the cars ride to stay very good while increasing the cars handling limits quite a bit.

Hmm, since these dampers probably wouldn't fit on a G35, and most likely won't fit on a Z prior to the 2007 model year, I wonder if strut tower bars that have dampers in them, instead of just solid, would make the same type of differences.

I have no idea if they fit a G or not. They are a 100% bolt on for ALL year Z's. My car is an 04 FWIW

Never say never they might, distances are different ahead of the front axle as well as the radiator bulkhead area's. We would need more info then can be easily found to know one way or another.

Having a damper inline on a STB would kill it's ability to do it's purpose, though I don't see any G35 STB being able to leverage mean force anyhow, their is a reason I don't have one.

Didn't know they fit on all year Z's... Nice! As for the G fitment, sure, there is always a possibility, but I'm not willing to spend the money to find out.

As for STB's, my front Stillen STB makes a noticeable difference on the track.

Can someone confirm they will fit on a 2004 Zed? I fitted RS-R Sports*i coilovers and am happy with the ride thus far, just fancy giving them a go... Is it worth fitting Anti roll bars at the same time?

I'd fit sway bars/roll bars first, and then go from there.

Just spoke with a local dealer's parts dept...and the price for the above list is approximately $850 with tax. I think there's a bit of a discount in there...so it might be a bit more.

Anyway...just thought I'd throw that out there.

According to the OP he got all his parts for a lot cheaper.
