i have the eibach pro's and it is pivotal that you at minimum and a Adj Panhard and at least and upper control arm....got it all, and lovin' every minute of it....the drop on my ride is tight!

 

You'll really enjoy the springs so much more if you make some other changes. First, get the Tokico D-Specs. Then move on to some other items. I couldn't be happier with mine. It rides and handles better than stock + looks like it should have from the factory. Go for it.

 

Did you just add the Ultra-Lites or did you replace the shocks too? Do you have any photos that you can post?
