Looking for some off the line traction without losing current handling

Only suspension mods I have done at the moment is Eibach Pro-Kit springs
which lowered my car 1.5"

I've got sub-frames that are soon to be put on as well.

I hear Upper/Lower control arms are a MUST, but what else can I get for suspension mods that wont screw with my handling?
Love the feel of my car at the moment with these tires and these springs, really seems to stick to the road and not much body roll at all(if any)

 

How wide of tires you got?

 

Widest I can go on a fox
245(9.6")

I hear if I flip the quad shock(which im attempting tomorrow again)
I can fit another inch under there...

 

thats not a mod, thats hurting your performance
