Bad Ass Suspension

I'm gonna start saving for some suspension but I don't know what to get.
The AGX/GC setup looks nice, and I have seen them in action. Price breakdown of those-
KYB AGX 4x150= $600
GC Coilover w/Eibach Springs= $399
So about a $1000 for those.

The Teins are about $1200, don't know much about these

The K-Sport's are less but I don't like some of the reviews.

The Progress are $1270.75, don't know much about these either.

Any other options?

I like to Autocross and I need something alot stiffer than what I have (stock). Right now I can get the left rear tire to come off the ground at least 6" (I have it on video), and that isn't acceptable.

Road comfort isn't that big of a deal to me, but it is a daily driver so they need to last long. I want the car to be lower as well, but not scraping the damn ground.

I don't know about spring rates for our cars either. Any input is appreciated...
