lowering springs

You are so right, my bad. I could have sworn that when I was looking for my spring they had H-techs, but now that I think about it, and look at the Tein usa site, I must have been looking at the 350Z H-techs.

The Tein coilovers are awesome. I had the Super Drift coils on my S14 with the EDFC (electronic damping force controller) which allows to control the damping from your driver seat, it was awesome. Some racing classes don't allow for it, so I would put my setting in that I wanted, and then just disconnected it. It's nice to be able to dial in or out understeer, and oversteer on the fly.
Now Tein as the EDFC active pro, which adjusts things on the fly for you with four wheel independent adjustments, front and rear separate, and right and left simultaneous adjustment. Pretty cool stuff if your into that sort of thing.

You might also look at the differences between and progessive spring rate and non, for your spring setup.
