Thinking about getting Eibach Sportlines. I know this setup is very low, but if I get koni yellow, will this make it a bit higher. Or better yet....can't I adjust the height using koni yellows??

 

I have Koni yellows and they have two grooves in them for the perch for the springs - one about stock height and a lower one to match springs that will be lower (shorter). They work great and are adjustable for firmness too.
