Ok, I've read a lot about members experiences with the Tokico D-Spec Shocks. Everyone seems to really like the improved handling they give.

However, the other thing I've noticed is that when people usually put on the D-Specs they are lowering the car at the same time with racing springs like Eibach, or Tein.

I personally have my G lowered right now, and I immediately felt a difference in handling from the lower center of gravity and improved spring rates.

1) So my question is, is it possible the D-Spec's aren't really that much of an improvement...it's really the drop that's causing the majority of the improved handling?

2) Has anyone ONLY changed the shocks...without dropping?

Thanks guys...

 

BUMP cause i was looking into these too and i would like to hear some info

 

honestly, the springs i installed a year before my tokikos. id say 85% of the improved handling came from just the eibachs alone.compared to stock sport setup, a smoother more planted feeling in the curves and at really high speeds. after installing the shocks i really felt very little improvement of stability/control . i was a little disappointed since the shocks cost more than twice the cost of the springs!

 

from what people have been saying here is that,
1/The d-spec shocks helps you with after market spings
With after market springs and stock shocks, your stock
shocks might wear down faster
2/Just d-spec shocks only, it might help with what people
usually complain about stock shocks is that the stock
shocks "bounces" too much. D-spec eliminates this
just my 2 cents,

i was wondering if the d-specs are specifically made for handling drop spring. does anyone know? do ppl normally get aftermarket camber and toe kits also?

 

Aftermarket toe/camber kits for the COUPE are a must...even without a drop or aftermarket wheels a lot of them have tire feathering problems, so you can imagine once you drop the car and put on wheels you'd need the camber and toe kits that much more.

Sedan, I'm not sure...I dropped my sedan on eibachs and I haven't had any problems with tire feathering.

Are the d-specs spefically made for handling a lower drop? Excellent question.

Everyone has a different answer about this, some people say coilovers are the only way to go. But if you're only dropping an inch it should be fine, because if you buy the D-Specs for the 350z, those are designed to ride an inch lower than the G35...so it should be ok. Not to mention 99.99% of people who get the D-specs have also dropped their cars.

 

Model DSP-9 are made for the Z and have a 3/4 inch shorter shaft than the DSP-7 for the G so they should work great with a 1" or so drop. I have them on with my Z springs.

 

i hear that the z springs are the same on the g......

 

I do not know if this helps or not but I have had 3 suspensions on my car.
1. Stock OEM sport (sedan)
2. OEM 2003 350z springs/shocks
3. put back to OEM sport sus (sedan)
4. OEM 05 350z springs + D-spec

4 = 50x better then anything that was on the car before.

 

alright! so whats the best springs i can get to get a little over a 1" drop with the d-specs? eek sorry im jacking this thread.

 

Yes!

I have helped two members here install D-specs on their cars and then got a chance to drive the cars after the install. In both cases the owner's did not have stiffer then oem springs and neither was lowered more then 1" (courtesty of oem coupe and oem Z springs). In each case I was struck by how much better the D-specs were then any oem Z or G shock. The overwhelming feeling was that a lot of R&D time and money was put into the valving science of the shocks to the point that IMO to anyone that install's the shocks, you will quickly understand why the money was spent. In short, D-specs when used within their spring rate capacity*, are a investment that does not require much searching to justify the cost.

*They are limited to peak spring rates of 450lbs, meaning Nismo T2 springs and Tom Motor sport sleave coilovers are a no no, since both exceed 450lbs in spring rate.

 

I just installed my D-specs this past weekend with my OEM '03 Z springs. Even with an initial setting of 4, I now know exactly what Gsedan35 is talking about. A great improvement, especially over my "bouncy" '03 OEM Z shocks. The damping control on the D-specs are much superior. I'm sure it'll get better when I start to experiment with the stiffer settings. 4 is comfortable but still feels a little floaty to me.

 

100% agree with Gsedan35
The added control to chasis dynamics is amazing with the D-Specs

Think about it...
OEM shocks control compression (down) forces only.
D-Spec control compression AND rebound forces.
Add to that, the D-Spec are completely tunable

 

They have been worth it for me, great investment.

 

D Spec is a replacement for the rear and front shocks?

When you guys say "adjustable" how easyit it to adjust, and from where?
