I purchased the front and rear mass vibration dampers that come stock on the 2007-2008 Nismo 350Z. Installation took about an hour. The rear damper, which mounts in the rear spare tire well, took about 20 minutes and was the easiest. Surprisingly for the front damper install, I did not have to remove the front bumper cover on my 2006 GT 350Z; I simply removed the botton engine cover/splash guard and then removed the plastic decorative covers from the left and right sides of the front bumper grill. This allowed access to the mounting bolts where you'll place the damper mounting brackets. Pics of the dampers and the install areas are below. Here is a complete list of parts needed to buy if you decide to do this addition. All of the parts were sourced from nissanparts.cc with the exception of the damper end-link bolts which Nissan, apparently, does not have correct part numbers for. I bought four 10mm-1.25 X 35mm metric hex bolts from Home Depot and these worked perfectly:

(1) E44B2-1A310 bar assy-damper front

(1) E54B2-1A310 bar assy-damper RR

(1) E44A6-1A300 brkt assy-damper bar, FR RH

(1) E44A7-1A300 brkt assy damper bar, FR LH

(1) E54B6-1A300 brkt assy-damper bar, RR RH

(1) E54B7-1A300 brkt assy-damper bar, RR LH

(4) 08156-8201F bolt (for rear brkt assy's)

(4) 08918-3402A nut (for front & rear damper bar end-links)

You will end up re-using the bolts that are already in place for the front brackets. Total cost was just over $620.00, plus shipping, from nissanparts.cc

I drove after the install and my first impression was that the car handled the on-ramps better without the tendency to want to over-steer or under-steer when it encountered bumps or expansion joints in the pavement. I do not track my car and perhaps the most benefit would be noticed or felt by those that do; however, this is just my opinion.

Front damper is longer than the rear:



Here is left rear bracket mounting location with stock bolts removed and the right rear bracket installed:



Here are pics of the rear damper installed with and without the spare tire:



Here is the cover plate that you'll have to remove (again from a 2006) from the far right and left sides of the front bumper grill opening to gain access to the bracket mounting locations:


Here is the driver's side damper mounting bracket installed. Again, you'll re-use the bolts that are already there:

good stuff...how about a more detailed impression though? (and way smaller pics!!!)

as for the pricing, they should update it asap...those prices are not at all accurate as of April 1 (everything went up)

nice..I dont need to take my front bumper off This might go on my car tomorrow then!

 

Ditto

 

What are some driving impressions? Pix are too big btw.

 

what else can u buy to get installed on ur z tht comes stock on the nismo zs

 

Basically all the exterior parts. Front and rear bumpers. Side skirts, wing and wheels.

Suspension: Yahama dampers. Not sure about the springs and shocks, but probably be better off with coilovers anyhow. Welding could be done too.

The NISMO muffler can be had, but again, an aftermarket part would probably be more worthwhile.

The interior bits are likely quite pricey and not worth the hassle.

 

I Disagree; the Nismo exhaust is just as capable as other aftermarket equivalents in non-FI situations.

Not trying to start an exhaust war on go OT on the OP, but I think giving sound, non-subjective advice is important. Worthwhile depends on what it's being used for.

 

Well I actually have a NISMO Z and while the muffler is decent for sound, there are aftermarket options that will deliver more power. The power gain might not be much, but again if you're going to bother, might as well.

The exhaust on the NISMO Z is only the muffler. The midpipe and y-pipe are the same as any '07-08 Z. The angle of the flange on the muffler is such that no aftermarket midpipes will bolt-on. If you want a complete "cat-back" system, an aftermarket exhaust is the way to go.

Oh just to clarify, the NISMO muffler is different than the Nismo cat-back exhaust.

 

I resized the pics.

 

can you explain how these work? compress like a shock or solid like a strut bar?

 

They're supposed to compress like a shock.

 

Nicely done.

 

basically the only thign i would need is the dampners



thx guys

 

I would be curious to hear from Resolute on his thoughts on these mass dampers. Even though Nissan used them on the Nismo Z and I doubt they would install something without cause, especially in light of the pressure the company is under profits wise (interesting read on Google news). But, I just don't have the kind of info at hand to even get warm and fuzzy about going to the expence and effort vs working on other aspects of the suspension/chassis.

 

I was referring to the Nismo cat-back system, and I did not know the Nismo Z system is just the muffler only. Thanks for the clarification!

 

Bump for driving impressions.

 

+1 ^^

 

What the hell are they supposed to do??? We already have a front strut brace, & some of us coilovers also. I understand they are on the NismO's, they look to tiny to do anything.

 

I hate to sound dense, but I thought the same thing. As opposed to hitting a 'performance' specification, they look like something added on to meet some corporate NVH (noise/vibration/harshness) edict.

 

first, given their location, they don't need to be big...they are controlling lateral movement, not horizontal movement. Second, it's a dual concept - Developed in conjunction with Yamaha, these dampers feature a unique damper assembly to help increase comfort and reduce suspension noise during low speed use, and simultaneously increase rigidity and handling during high speed use. That is the marketing info side of things - once I put the front one on my own car, I promise a complete write up on my impressions
