Spring relocation and handling in the curves

Hello all, I have finally gotten my dart on the road, and am planning on enjoying it for a bit before any further major work, such as mini tubbing it. After driving it though, the main issue I'm having is traction, efi 5.7 hemi, 5 speed manual, only 7" rear wheels, but even with 3.23s I can get it sideways in third if I'm trying. The car is light (under 3k with me in it), and is definitely a blast to drive, but want to possibly auto cross and drag it a bit, and no traction = slow. I have a 3" relocation kit on the shelf, I just don't want to hurt the handling of this car through the corners. I have "massaged" the inner fenders and lips as far as I can, I could probably squeeze an 8" wheel with the right wheel, but I don't want to buy wheels and then relocate the springs, buy wheels again, etc. Is anyone using relocated springs on a corner carver, or is it best only for drag racing?
