Quoting turbowop:
I got ahold of the guy that sold me the JICs. He says the springrates are 8k front, 7k rear. Or 450lbs/393lbs. I don't think that's far off of what the spring rates were for the Teins, but the valving is much softer making for a better ride on the street.
Yep, I rode in an Evo once with 14k/16k and this thing rode like silky smooth buttah - firm, yet smooth. No pitching or pogo-ing. Huge bumps, you knew it was stiff. But, normal roads, just smoother. Why? Custom built Motons. That's why! /ubbthreads/images/graemlins/crazy.gif sh*t was valved to handle the spring rates. I was soooo jelly!
