SOLD: $700 + shipping. Good used condition. Honestly, I never really touched them much. They came on my NB2 when I bought it and I replaced them with Gen 1 Xida's my friend had after 2 track days. They seemed fine, but someone gave me Xidas. So like, yea.

Do you have actual pictures?

Any idea on what rate springs are on them? Any of the options on them? Helper or billet race mounts?

 

I got them on the car that I bought, so i dont know anything about the options they were purchased with. I called GC with the numbers on the springs and they told me it was 670lbs/in front and 430lbs/in rear.
