Thanks for actually making a proper post and stating what your issues and goals are.
The springs on the Nismo are constant/linear rate. On the track this means they are very predictable and are easy to match a damper to. Down side they are the same on and off the track.
Progressive springs, like those found on KWV3s, are progressive. These give you a nice soft ride for cruising around town and can be just as firm as you need for hard cornering. The problem on the track with these they are less predictable and hard to get the dampening just right because the spring rate is always different.

I'd recommend looking into getting KWV3s. They don't drop the car much and are good all around.
