Stock battery box is rusted to hell, my friend said he can make me one, so we'll see.

Kepping the battery in the back of the car will make turn in quicker. Not trying to swing another 60lbs on the front axels.

Really? I figured the weight balance would be better.

You can compensate for having more weight in the rear with staggered tire sizes front and back. My battery is under the passenger side headlight. Being in front of the axels is even worse.

So what do you suggest I do?

Fiero store sells a replacement battery tray, thats what I would do.

What about shauns box in the trunk? Or your under the headlight thing?

You can do whatever you want, but if I did it again I would put it back in the stock location, assuming I have enough room with the N*.

Having it in the stock location also makes it handy for doing engine swap electical work.

I don't recomend putting it under the headlight, inconvenient if you ever need a boost.

Stock sized battery fits the stock location with a Northstar in the bay... but it's snug.

Don't confuse weight distribution with moment of inertia.
The point of putting the engine in the back is to concentrate the mass of the car and reduce moment of inertia. Moving the battery to the front works directly counter to this objective.

lol, see norm's reply on your РFF request :thumbleft:

It was explained to me that since the majority of the fieros wieght is in the back, the car will "push" and understeer much like a porsche.

Now because of norm I have to build one and show all my receipts.

lol "buy my shit bitch"

I'm not sure why he's thinking it'll cost you over $80 to make one yourself. some scrap metal, heavy gauge wire, and you're all set.

Thats what I was trying to describe without actually saying MOI.

Battery under the headlight is probably the worst location for it.

My trunk may be consumed by a bandbass sub box ported into the cabin if we can figure out how to route a pipe safely into the car. I can buy 4ga for $.89 a foot and 1/0ga for $1.75 a foot all day long (Car audio quality) whereas norms comes with like 8ga. I have a roll of fiberglass, all I really have to buy is resin.

Yeah, that's about as bad as it gets.
Putting it in place of the passenger seat would be ideal.
Dropping it straight down and mounting it behind the right quarter panel wouldn't be far off. You could hinge the 1/4 panel and use 1/4 turn fasteners to hold it shut.

ugh, you guys are confusing me!

Vaguely like the C4 Corvettes, except behind the door, not in front.

This might not work on the '87-88's because of the Evap tank mounted there, though.

Let me summarize, leave it where it's at :thumbleft:

The expansion volume is actually about the same height as the stock battery location. What I'm thinking of would put the battery below that, as low in the chassis as it can go.

Now that you mention it, I do remember it being fairly high under the bodywork... It's been a while since I've done much work on my car.

A very low mounting point would help keep the weight below the c/g, too.

I'd just worry about it being split open in an accident, since there's no real structure behind that quarter panel down there.

But, realistically, on a car that isn't an all out racer, you'll never be able to tell where the battery is while driving the car anyway. :thumbleft:
