Just went back to stock the other day because I'm getting ready for the track. These have a progressive spring rate so they are only a little bit stiffer than stock when driving normally but become stiffer as you push it harder.

Lowers:
0.75" - Front
0.60" - Rear

Here's how they looked on my car: https://www.s2ki.com/s2000/topic/922...olished-volks/
