Hi all. I have been eyeing the 2009 370Z Nismo suspension kit and would like your feedback. I have an 06 6MT sedan. My goals for the setup is rather simple: less roll in the corners, less squat when accelerating, not completely give up compliance to performance (but definitely some). My friend has an Audi S4 with 600lb springs. The car is pretty incredible in the corners, but is beyond my personal harshness upper limit. I have also looked at some of the well-liked coil overs through this thread, pss and the like. They all offer quite a bit of adjustability/flexibility. However, I am interested in understanding how the 'out-of-the-box' Nismo's would compare with some of the higher sprung (and higher cost) adjustable coil overs. I know what 600lb springs feel like on a *different car*. But, given this and what my stock spring rates (314/342) the nismo numbers seem to fit well with what I want (492/336-672). I know well enough that different cars feel/work differently and linear increases in spring rates do not equate in a linear difference in cornering/compliance. That said, I am interested in your opinions and a bit of hard numbers for the following:

1. Will these bolt in? Will I need toe/camber adjusters?

2. What will be the adjustment in ride height with them? It would be great to go down 0.75" to 1", but my heart is not set on it.

3. Anything to keep in mind if I put in a set of the coupe's 19" rays?

4. Thoughts on the S-specs vs some of the good coilovers?

5. This is perhaps the most important: can you point me to a few good resource pages to answer some of the above questions myself? Teach a chap to fish, and all... the more technical the better...

Thanks!

 

alright, how about a different approach....

... does anyone know if there are any mounting differences between the S-tune suspension kit and an 06 sedan? Basically, will these work? Should I be aware of anything?

... Should I expect any different of a drop from what Gsedan35 says about typical 350Z springs (about 1 inch)?

Thanks! Jason

 

I am planning on getting the Tein S-Techs for my 2006 Sedan and would like to know if I am going to need adjustable toe arms? I already have SPL Ajustable Front A-Arms and Stillen Rear Adjustable Camber arms.

 

no info anywhere on Tanabe coilovers specifically Pro S-OC

several people asking - but no real reviews (here or anywhere)... very minor response in another thread.

I wonder why no one has tried these coilovers?

 

I wish I got around to this forum and especially this thread earlier. I am new to moding G's but this car has way more products support than a lot of other cars I've seen, which is great and bad at the same time. I have an 04 X, and I noticed that not a lot of people have the specs on the awd version. I read somewhere that the front shocks are different than all other G's and Z's. I am thinking of a Z/couple spring drop. Just wondering if using the stock shocks would be good enough in the long haul. And also, does anyone know what spring rates are for the OEM X? Feel free to make suggestions on the springs. I am open to any suggestions.
Thank you!

 

G35 Coupe (V35) 03-06 Spring Rate 5.5 / 6.3 Down Rate 1.7 / 1.3
G35 Sedan (V35) 03-06 Spring Rate 5.1 / 5.0 Down Rate 1.7 / 1.5

Not sure if this covers the X

 

This helped me out with my decision process, thanks.

 

Just found out from Bilstein, they approved the pss 10 for the 2nd gen sedan.
so the same part # for G35 coupes and sedans through 2008. I am thinking of selling my impuls and getting the adjustability of the pss 10. I think the drop from stock is supposed to be between 1 to 2 inches front and rear. Maybe could get by without camber adjusters if near the higher setting

 

can someone plz explain spring rates to me? since my car has Front:314 Rear:342 does that mean if i get springs with 358/274 that its gonna be more bouncy or what? i hope this makes since to someone...

 

the numbers represent foot pounds. Your current setup requires 314 ft lbs to compress the front and 342 ft lbs to compress the rear.

If you get the springs mentioned the front will be stiffer (takes more force to compress) and the rear will be much softer (taking 68 ft lbs less to compress).

Will you notice a difference in drive-ability? Possibly, but probably not much. If you have decent shocks in the rear the rebound wont give you a lot of "bounce"... it may roll a bit more in hard cornering, but soft front are more noticeable in this respect. Since the new springs have a stiffer front spring rate, you may notice improved handling in hard cornering and possibly a little stiffer ride. In either respect it wont be overly noticeable.

The spring rates on both setups aren't very stiff - so ride quality should be pretty good - more comfort than sport.

 

thanks for the info. so if i get springs with rates of 386/402 there will be better handling all around and less roll right? also whats the difference between progressive and linear?

 

^^^ yes. But as with other types of mods it’s the sum of combination that makes things work… better handling is a combo of suspension mods - anti sway bars and wider tires with decent grip will also show noticeable improvement.

Progressive means the spring rate starts soft and progressively gets stiffer... that's why they will give two numbers, one is the force to initially compress springs, the second is the force it takes to further compress. The benefit to progressive is ride comfort - with the right progressive spring rate you can have nice daily driving comfort with decent sporty performance handling. I like Eibach Pro Kits spring rates a lot - very comfortable and very performance capable.

Linear spring rate is just as is says - the force it takes to compress is linear - the same throughout the compression of the spring. It is not gradually stiffer like progressive. The benefit is consistent firm, controlled cornering -and much easier to anticipate and control the way the car will behave... the draw-back is generally a stiffer ride.

For track use and performance goals, relatively stiff linear spring rates are best... for luxury ride quality, soft linear or progressive spring are best... for a combo of both, progressive springs with rates that are not too far apart works best for me.

 

I have a 04 coupe. I am looking to lower my car and not have to get camber kits and all that stuff. Would the Tein H-tech G35 springs be the springs I am looking for? Thanks for the help.

 

My sedan is lowered with Tein S-Techs and was wanting to replace my OEM sport shocks. Which one would you all recommend.
