Some drag racers remove a front mounted battery and place it in the trunk.
The effect is that whatever the weight you just moved is worth twice the weight.
Some drag racers place a super heavy battery in the trunk for better traction.

Since you took it off the front and also added it to the back.....

When I first looked in my trunk and found the battery there STOCK,

I thought that was pretty cool.

Dodge is the first mfg'er to encourage a person to race their car...
All the stuff in "the box" , tuning specs right down to the shock settings and air pressure,
Red key fob and black key fob.

I'm a road course guy, and I see nothing wrong with a lightweight battery.
In the trunk is fine with me. If I want to save more weight, I have a long list..... lol

and I'm not talking.....
