Where does a Subaru (backwards Corvair) have it's battery on performance models?

Folks,
I want to thank everyone who responded, both on the list serve and
privately. It's been helpful, and lead me to re-think exactly how Doran (my
son) and I will do the battery. I'm still convinced that moving it will be
helpful in reducing oversteer, at lesat partially. Between eliminating the
spare tire totally (lightening the car as well as taking weight off the rear)
and moving the battery, there should be a noticeable effect.
Warrren, I agree with you about the "polar moment" caused by moving the
battery. My understanding of these "physics" is that you probably want the
weight between the axles if at all possible. On the other hand, the other make
of cars (other than Chevies) that I own and work on are BMW's. My 88 M5 came
from the factory with 255 hp out of 213 cubic inches (it now makes about 290)
and idles and runs fine as a daily driver. The 01 MCoupe I recently bought my
wife makes 315 hp out of about 195 cubic inches and is fine as a daily commuter.
These folk do know a thing or two about making performance cars, and on the M5
the battery is in the trunk, BEHIND the right rear wheel. I have often thought
that it is too far to the rear, but that may be the result of where there was
space. (The MCoupe has it under the rear floor, centered, but still just behind
the reare axle.) The car has run through the merry-go-round at VIR in very
"spirited" fashion and then turned 120 on the front straight, all with me and 4
Boy Scouts in it (during the "parade laps" that they let you buy). It is a
heavy car --- about 3600 pounds --- but very balanced and almost "tossable". So
I'm convinced that getting the battery off the rearend is the right thing to do,
but maybe as low as possbile in the trunk, between the front wheels.
