So i've installed KYB shocks and struts last month and i'm looking for a good set of springs to match. I went through 50+ threads on the subject and just ended up dizzy. Here's what i'm looking for:

I've got a 91Z, 305 w/100k miles on it. It still has the stock springs in it and it's just too stiff - I don't like feeling every bump. I've read about how great the Eibach Prokit springs are but i don't want my car lowered (i don't believe the stock ones are sagging and still i scrape the car ALL OVER southern California, that plus with all the problems i've read here as a result of lowering the car all make it not worth it - right?).
I'd gladly sacrifice totally killer cornering for a setup with decent cornering with a smoother ride as this is a daily driver.
Which quality springs am i looking for?

thanks much!
