Looking at getting this, I already have the D-Spec shocks and struts, does anyone have it yet? Does it suffer the same problem as the Hotchkiss and others with the one side lower than the other? What is the preciese drop F/R on these? If you have them, how are they?

Thanks.

supsup

i like to know that too! anyone???

well
i think the tokico springs are better match for those shocks
since the spring rate are design for those shocks right??

And how do they compare to the NISMO springs.

They will drop the Z 1.2"

They are linear springs and use 375/375 spring rates

Should be a very nice combo, just wish the drop amount was less.

Tokico actually makes the Nismo S-tune setup.

They differ in that the D-spec is a more advance shock design and it allow's for the owner to tune the shock stiffness with it's double adjustable design (compression and rebound) The S-tune uses progressive spring rates with higher peak rates whereas the D-spec/spring combo uses linear springs that have a consistent rate but are not as stiff as the S-tune's peak progressive rates


Nismo S-tune (twin tube construction, uses progressive springs, especially in rear)
350Z/G35 Coupe
Spring rates 448/504


Oem 350Z spring rates are as follows
2003-2004
314/342

2004+ on 350Z coupe and all roadster's
314/427

"allow's for the owner to tune the shock stiffness with it's double adjustable design (compression and rebound)"

just to clarify, the tokico's aren't a true double adjustable. you cannot independently adjust compression and rebound, they are adjusted together with one dial. that's probably what you meant, but just to clarify for others.

btw G did you get my pm on the tanabe's? (sorry to be a pain in the a**)

ok ... so the D-Spec shocks will fit both g35 coupe and 350z right?

cos' i just PM revhigh
about the D-Spec shocks and tein-S springs
and they say it will not fit g35 coupe...!?!

There are two models of D-Spec shocks. The DSP-9 model is for the Z and the DSP-7 model is for the G35 Coupe/Sedan. Both will fit on both cars but it would be ill advised to put the G-coupe version on the Z. Having said that the DSP-9 model is a bit shorter than the DSP-7 by like 1/2 inch to match OEM length.

Adjustable shocks are defined by what they adjust for, not how. When a product can adjust more then one thing and do that independently, that ability is a addition and get's mentioned as such since it's a key benefit. With the D-specs ability to adjust both compression and rebound, they are double adjustable.

SA= Single adjustble (rebound only)
DA= Double adjustable (both compression and rebound)
4-way (high/low speed rebound, high/low speed compression)

All shocks made for the Z fit on G35 coupes and RWD sedans, no exception's, I can't tell you how many variation's have been on my car or how many I've helped install on other G's. As mentioned the rear shocks on the Z D-specs are shorter, and will install on your coupe. I know I installed a set on a friend's G sedan.

Does your coupe have oem 19's by chance? Not sure that I'd go with G35 Tein S-techs if that's the case.

Gsedan35- I have a 2005 G35 sedan and plan using 05 Z springs, would you recommend DSP-7 or DSP-9? Thanks.

supsup

i have the 18" wheels
i just wanna makesure those shock will work with those springs
and it will not bottom out easily cos the rear shock is shorter.
also why is it bad to have tein S with the 05 19" wheel??

Just thought of something that is in addition to my pm reply to you. Be mindfull that your spring choice does increase rear spring rates by 24% and that your not just lowering the car 1". While testing after install, walk up the the handling limit's slowly as at the limit behavior likely won't be the same (especially if you haven't had the car aligned yet). Investing in adjustable sway bars would be a good idea setting them to med/med then testing to see if slight chages in bar settings are required.

That's a pretty good drop over oem, go with the Z D-specs.

Having a 05 G coupe with oem 19's means your car would have 427lbs rear spring rates, all other G coupe production with oem 17's and 18's have 342lbs rear spring rates. Going 36% softer in the rear, while increasing the front spring stiffness 14% isn't a route I'd recommend. Though I would not blink a eye if that rear rate drop was limited to 342lbs or 330lbs.


Tein S-tech G35 coupe (fronts are progressive, rears are linear)
Spring rates in LBS 358/274 (final rates only, softer intial front progressive rate unknown)
Stiffer or softer then oem springs by F+14% R-18%

Stiffer or softer then G coupe with oem 19's
F+14% R-36%

From 350Zonline:
The spring rate are 275 Front and 275 rear.
The springs lower the 350z/G35 1 inch.
Posted by Gsedan35:
They will drop the Z 1.2"
They are linear springs and use 375/375 spring rates
Should be a very nice combo, just wish the drop amount was less.

On the Z store site:
These performance springs lower 350Z's from 3/4" to 1" from stock ride height.

I hate to buy these and find out that they are not what I wanted. I want a modest drop that is a lttle stiffer than stock, but allows alignment without buying added suspension pieces. The confusion about what these actually are and do, and the for sure lack of information from Tokico, are preventing my purchase.
I will not buy Hotchkiss because of the possible lean, and lack of a real explanation for it.

My data comes from Tokico themselves, 1-800-548-2549 ask for Ray. I did not make the call myself, but I have zero reason to not believe the data is fully accurate

G35 - DSK507 - 240f/300r - Linear Springs (G coupe not G sedan)

350Z - DSK512 - 375f/375r - Linear Springs

Both are supposed to lower each respective vehicle 1.2"

I was hoping you were wrong as I wanted these springs, but that is just too low for me. Too bad vendors can't be troubled to post accurate information.

Call Tokico Direct!!

My numbers came from Tokico.

I was responsible for all the testing on my car before they came out.

From your web site.

"The spring rate are 275 Front and 275 rear."

"The springs lower the 350z/G35 1 inch."

Something tells my you made the simple mistake of typing 275 twice when you ment to type 375 twice. Two factor's, one Ray at Tokico recently gave out the spring rates as 375/375 and correctly I.D. the kit's DSK part number sig. And, it makes doesn't make sense to have 275lbs spring rates which would be softer then oem. No other aftermarket linear spring sold for the Z33 goes that low and for good reason.

RSR 345/417
Tein H-tech 358/375
Swift 336/364

Also, you cannot list the spring as offering the 350Z/G35 a 1" drop. This is impossible because the G35 side as the car does not have the same oem ride height, any 350Z spring run on a G35 coupe will drop the coupe a additional .5". Same thing applied to a G35 sedan will see the drop amount a additional inch. Don't get me wrong, I'm totally for using 350Z based stuff on the G35, but enduser's have to have correct data to base decision's on.

Ray also mentioned that they have a G35 coupe specific application spring rates are G35 - DSK507 - 240f/300r This is the application that doesn't make sense, but it would not be the first time that aftermarket has viewed the G35 as being driven only by those wanting soft luxury.

Well maybe you are right my numbers came direct from Joey in mareting over there . Rays know what he is doing and his number are probably more accurate.

My tokico sping rates were only an inch on the Z becasue of clearence issue with the Z stock.

Call the number and ask ext 214 for Joey he sell them all day he tell you whats up?
