Battery relocation for HANDLING (not drag) - best spot to mount?

Leave the battery in the factory location and invest your money in sway bars, shocks and tires.
Talk to the Guy's that autocross.

I’ve got the Helwig hollow front sway bar, 1.14” torsion bars, QA1 tubular control arms, QA1 dynamic strut rods Hotchikis leaf springs and their recommended Fox shocks and an Eaton Truetrac diff with 4.10s. I added torque boxes and subframe connectors and still found a net 150lbs or so to shave off of the car without making it look like Swiss cheese. I just had the alignment dialed in according to the more extreme end of the “Skosh” chart which helped a lot! Tires are a sore subject since I’m dedicated to the 15s (don’t get me started) so relocating the battery might be a good next step.
