Racing battery question

Oh and I install my battery in the dead middle of the trunk, as low as possible. just behind the differential cover of my dana. [made a battery holder which allows the battery to be below the trunk floor] then, I tune the chassis for straight, clean equal lift take-offs! I use a ladder bar rear suspension with double adjustable shocks. I also use the wheelie bars...to sometimes fine tune the lift and reaction of the car to the right by adding 1/4 to 3/8" difference from right wheel to left wheel.
