Springs and shocks
There are many spring and shock options available for your car.
In addition to the normal aftermarket springs available(eibach,
tokico, suspension techniques, intrax, etc, etc) you can also
use springs from other 300ZXs. 87-89 turbos have fairly stiff
springs and the springs from an 88SE(SS if you prefer) are
about the hardest springs you can get without special ordering
Some common aftermarket spring rates are shown below. Note
the eibachs, they are variable rate springs. Variable rate
springs are often touted as "wuss springs" because of their
softness when uncompressed. Linear rate springs are generally
better for performance but much worse in the ride department.
All the non-nissan springs below will lower your car approximately
1/2-1 inch from stock depending on the condition of your current springs.
- Best performing springs: SS
- Best performing springs if you fix camber in ther rear: Suspension Techniques
- Worst performing springs: Eibach
- Best shocks: Bilstein or Tokico adjustable depending on who you ask.
- Only KYB shocks need the adaptor kit to be used on cars with stock
adjustable shocks - Tokico adjustables and Bilsteins fit properly in cars
equipped with stock adjustable suspension(ie. all turbos except for the SS).
SS springs are a rare commodity now, as the Nissan supply of them
was depleted in March 2000. A trickle of SS springs are available at
various large dealerships as they pop up in Nissan's inventory in Japan.
Check Courtesy Nissan if you insist on buying them new($112 EACH, $85 EACH
from courtesy. You need 4).
Since they were so popular, they should
start popping up in junkyards. All stock springs are color coded
for their application - SS springs have white and purple marks on the
rear springs while the fronts have orange and pink marks.
If you get harder springs you also need firmer shocks to hold the
springs. Tockico non-adjustable shocks are the most popular and
are firm enough for all but the stiffest springs. Be forewarned,
if you use SS springs the tokicos are not firm enough to hold them.
Bilstien HDs and Tokico adjustables are the most popular high end
shocks and are firm enough for any springs you can get. KYB, Koni,
sachs-boge, and many others make replacement shocks as well.
Be warned, kyb and sachs-boge are not performance shocks as they are
Note: SS springs have white/purple color codes (paint dots)on the rear springs and orange/pink color code on front.
