Anyone know if the Tokico D Spec are available as complete
kit with springs as they are with some other cars,
Or just the struts/dampers?

 

no springs. they do work well with aftermarket lowering springs.

 

Thanks,
I know there are two models available.
One for the Z & I think one for both coupe & sedan.
??
If my sedan is lowered to the ride height of the Z,
should I get the one for the Z?

 

You should consider based on the weight differences of the two
cars and if you plan to carry many passengers.

 

same shocks im planning to get... not sure if they would fit in an 05 sedan.. would it ? the site says 03-04 g35s

 

Weight difference is not really the issue.

Spring rates would be, but not in this case
I have the '04 sport sedan.
The Z, coupe & sport sedan all have the same OEM spring rate

314f / 342r

& D-Spec are adjustable for both rebound and compression damping.
(but not independantly)

I was thinking that since I'm lowered to Z ride height....
the length of the Z strut/shock would be more suitable?

 

>The Z, coupe & sport sedan all have the same OEM spring rate 314f / 342r.


Interesting.

 

I did not find a colation between ANY shock measurements that I took when I had 350Z D-specs in my hands that revealed the shocks were shorter in a meaningfull manner to oem sedan shocks. Which was weird given that oem Z shocks are shorter bodied then oem sedan shocks by 3/4" or so. I looked at body length and extended piston shaft length amongst other measurements, somewhere I have them written down.

On the issue of which version to get, buy the 350Z version. Why do I say that. Given that the 350Z D-specs I got a chance to drive on were not near as stiff as Tokico had led me to believe*. I would not care to find out that maybe, just maybe the G specific D-specs are valved softer still. Set at half way up their stiffness adjustment settings, they were just a bit firmer then the oem sport sedan and G coupe. Which is exactly what the owner wanted.

The D-specs offer a really nice ride and drive quality. The overwhelming sensation is that they spent a lot of time in R&D getting the valving down pat. Overall you quickly realize that your money was well spent, well that's what I say, they weren't my shocks I was simply graciously given a chance to drive the car home from the install location.

*What Tokico told me. They told me that the shocks would be adjusted to be a bit softer then oem 350Z shocks, just as firm or MUCH firmer. Thing is, I HAVE the 350Z suspension on my car, so I now exactly how stiff it's shocks are.

 

How much do the 350Z struts go for?

 

Tokico 350Z and G35 D-spec shocks sell for the same price. They show up on ebay for $499 shipped. Of course as alway's give a forum sponcer a chance to take the business and make the sale before you buy.

 

Gsedan35;
Thanks again for your input.

My initial thoughts were to go with the Z model,
due to the expected difference in body length.

Evan though there is no difference in body length,
based on your experience it still sounds like the Z model is best way to go.

Thanks

 

I have the GCoupe versions and it's set on 3.5 in the rear and 4 in the front and it still seems noticeably stiffer than stock...not subtle. However, I did change both springs and shocks at the same time so maybe it's the springs that's causing the slight bumpy ride quality (from stock). I had it first set on 3 in the rear and 4 in front.

 

Thanks. I guess with the benefit of having adjustability, the
D-Specs might be easier to use.

Is it really true that the G sedan, coupe and 350Z all use
314F / 342R rates?

 

Yes.

This is a example of how a company MIGHT get the wrong idea. Eibach's development car for their sedan springs was a non sport, which uses springs that are 10% softer. So, if they were to claim the sedan uses softer oem springs, that's why. They didn't R&D the stiffer sedan with sport and wouldn't know any better.

I got the spring rates for all the cars by either outright owning the springs or by the kindness of forum members. I take several carefull measurements of each springs wire diameter, ouside coil diameter and the number of active coils. I would like to measure G35X springs and springs off a 05 coupe with the sport suspension.

 

Thanks. Yeh, I read that the non-sport used softer springs but didn't
think they would use all same rates on the other 3, especially the 350Z.
