battery relocation to trunk !

heres the deal.
We(autozone) do sell a marine battery sized box, but its not sealed.
I used the moroso sealed box(the blue one) and the summit wiring kit. Its scary that my car lifts about 1/2" when I pick the battery up out of the stock tray. So it must be worth something.

I know this is a silly question, but is the advantage of moving the battery. It doesn't make the car lighter. And theres actually more weight in the back. And when i buy 2 weeks worth of groceries and put them in the back of my hatch, I don't get more HP???? If that was the case I would leave my sandbags I use for winter (stangs not the best for winter driving) in the back. . I really need a logical explanation if someone has the time

I believe that the advantage is the weight disribution differential. By taking the 40 pound battery and taking it out of the front (which are too heavy on Mustangs anyway) and moving it to the back (which is really light) it changes the weight distribution by 1%. I know this doesn't sound like much, but it is supposed to improve handling a little, and of course, give you more traction.

definately weight distribution is the key. My lightning is balanced much better than a mustang, even the 4cyl. Kind of scary.

How's this...it's like adding sandbags in the trunk for traction, without adding any overall weight to the car...

This seems like it may be a decent idea, does anyone happen to have pics of a relocated battery in the back of a hatchback Mustang?

I don't have pics, but it is an easy Saturday project. If you don't have to carry a spare tire w/ you, you can put it in the spare wheel well and have it pretty un-noticable and as low a center of gravity as possible. I did this, but I have never in 14 years of having my LX had a flat - knock on wood. So...I yanked my spare and jack, put mine in the spare wheel well. Lower's the back about 1/2".

Make sure you put a 100 amp fuse (I think that's it) on the POS cable near the battery, so if it ever grounds the car doesn't catch fire. Supposedly cheap at Radioshack - I still haven't done that yet myself.

Easiest place to run the POS cable through the firewall is by making a small hole in the steering input shafts rubber boot. You can run it under the plastic interior pieces until you get to the door sills, then under the carpet and up to the boot. Make sure it's good wire w/ good insulator, leave slack in it, don't force it around any rough edges and keep it away from edges so it won't rub.

The NEG cable you can just ground anywhere to the body in back. I drilled a hole in my spare wheel well, removed the paint, put a large bolt through it. Works great.
