See Details Below. It features the aluminum pillow ball upper mounts and independent ride height and spring pre-load adjust-ability. With all the adjustment and spring options, it is possible to set up the vehicle to meet all situations and scenarios. Though this does not sound like a lot, it can make a big difference performance-wise when the dynamics of sprung vs.
Sprung weight is defined as a parts weight while in motion or constant oscillation. Un-sprung weight is the actual weight of the part as it is at rest or not in motion. Sprung weight is calculated to be approximately time its un-sprung weight. Therefore a coilover assemble that is time lighter than another can be as much as lbs.

Just google them. Custom wound coil springs would be your best bet for stiffness and ride height. Coupled with some bilstein struts you'll be golden. If you want height and ride adjustability, coilovers are the only option. And in that case, Stance coilovers are your best option. And stay the hell away from eibach or tokico if you want decent springs.

Whats wrong with tokicos? They give the car a crazy raked stance and the spring rates are way too low. The rake is kinda bad but they are the best thing in my opinion compared to coilovers. But they were so soft i hated them i had alot of squat and body roll with them vs what i have with my z3r gray z or my st front and ss cut rear on the red z.
Without going coilovers, the best off the shelf combo is probably Konis paired with a second hand set of Z3R or ST springs. Bilsteins would go well with either spring, and be more budget friendly.
Coilovers or custom springs would open up a world of options in spring rates and lowering though. I've got a set of SS springs and Konis that should be making their way onto my 86T. I don't care about lowering it really blasphemy, I knowbut it will handle way better than the worn out stock springs and crappy Monroes the PO swapped in. No idea, I went directly to coilovers because I wanted the height adjustability. Don't mean to threadjack or anything, but here is a quote I received from coilsprings.

Down to bare metal by TWA88T.Even with k miles on the odometer, my zx seemed to handle really well. At interstate speeds, however, it would tend to track back and forth and would wallow a bit over bumps.
As with every other component on the car, the suspension received a complete overhaul. To begin, completely disassemble the front suspension on one side. If you have the engine out of the vehicle, you can completely disassemble the front suspension. If you are not comfortable with the tools or the procedure, then do not attempt to disassemble the strut. While you have the suspension apart you can also upgrade the control arm bushings. Click here for the write-up.
While apart, replace the hub wheel seal and repack the bearings. If your bearings are in poor condition, you must also replace the bearing races. If this is necessary, drive them out, carefully, with a drift punch and tap new races in. Also, be sure to use a good quality, high-temp, disc-brake wheel grease.

Heads, pistons, turbochargers, radiators, exhaust Engine Management.Do you want to better the handling of your Z31 or get a better Stance? Is your Rear sagging worse than Old lady Boobs? Well this information will help you determine the springs your Z came with so you can replace them with stock units or after market upgrades.
At this time There are many spring options available for the Z31 ZX. In addition to the normal after market springs available Eibach, Tokico, etc you can also use springs from other Z31s. All Z31 springs interchange with no fitment issues. You can use any Z31 Spring in any year or model, in-fact the to turbo models have fairly stiff springs vs the Non turbo models. While the Z31 springs will fit in any Z31, there will be a slight shift in ride height depending on what model you have and what springs you end up using.
If you choose to stay with stock springs the spring set from a Shiro Edition are stiffest springs you can get without going after market.
Some common after market spring rates are shown below. The idea of a progressive variable rate spring is to allow a smooth ride when driving normally, and improved body control when cornering hard.
Variable rate springs are easy to spot because the springs are not symmetrical.
Typically, one end of the spring is wound tighter than the other end with the more tightly wound end being the softer part of the spring. As the spring is compressed, the soft coils on the tightly wound side will collapse, coming into contact with each other. When this happens, the rest of the spring starts to compress at the second higher rate. All stock springs are color coded for their application.
Use the charts below to Identify the model and Specs of your Z31 Springs. You can do so by cleaning your spring and locating the color code.
It will be 2 dots painted on the spring coils. The color combination will identify the spring model and with this you can see the rates listed in the tool below.
