I Have 245/35/20s front and rear. My rear tires already tuck with no finger gap at all. I have a stereo in the trunk so I am assuming it just sags abit and that is why it is so much lower in the rear.

I already ordered eibach pro kit but I am thinking about just installing the front springs only. I don't like the rear sitting that much lower than the front.

Here is the main question. If I install the rear eibach springs, will it lower it 1 inch from where it is today, or will the springs be stiff enough to handle the weight of my stereo and stay the same height, as my stock sagging springs?

I want my springs to be a bit stiffer for cornering but I don't want the rear tucking the entire tire and the front sitting just above the tire.

What do you guys think??
