I just phoned Neuspeed to confirm the rates of my Sofsports 96-00 civic(EK).
I have searched the forums and web and found many different rates for these springs, so I'll post what neuspeed told me for anyone out there searching.

Neuspeed emailed me these "working" rates. These are the rates the the suspension rides at.

300 lb/in front
190 lb/in rear

I got the advertised .75" drop as well. I'm running them with Teg' Bilstein HD's and a slightly trimmed front bumpstop. The ride and control is sweet, I just need a comptech swaybar kit now.

I am very happy with these springs. I wanted a significantly firmer ride with
only a small drop(or none at all). This is exactly what these springs offer. I'm dissappointed that Neuspeed discontinued them for the Civic. (due to lack of sales)

The rears are progressive. I am not sure about the front springs though.
It appears that the rates are similar to the ITR rates/or even a bit stiffer.

Cheers,
Josh

Back from the dead. Just wondering if you have pics of your car with the .75" drop.

 

I searched for a few and found noithing, but, you could take a look at a CTR/ITR.
They are about 1'' lower then normal.

Not the .75'' but I doubt .25'' makes a big difference.

 

Not sure he'll respond:

We could start a seance then ask the spirit a question.
