rear mount battery
I'm having trouble finding any results here on the rear mount battery.
I found a DIY on SVF but it seems that my "buckets" are reversed driver to passenger. Is the driver side "bucket" normally bigger than the passenger side? (2007' LS2)
Pass side.

I think that's the OnStar module. There's a fairly recent thread about a guy relocating that module, and had all kinds of trouble. Maybe due to other factors, but you might want to search for it. And search for posts, because it wasn't a thread about that, so it's going to be harder to find. You might also want to research differences between an automatic and manual GS to find out what's different (auto GS doesn't have battery in trunk). Good luck.

You have to keep plug J4 connected or you want be able to start the car. You can unplug J1, J2 & J3, but that won't help you agin any additional space.

Do you have navigation? I don't so all I have is the battery there. If it is Onstar maybe they put the box somewhere else in the car but I thought that's what's on your windshield. Maybe that's just the antenna.

So lets see.. automotive engineers spent alot of time and money designing the car and getting the corner weight so close you can barely tell the difference and then you come along and all of a sudden you know better?

ps. why would YOU put a MGW shifter in a car the engineers spent so much time/money developing?
Back on topic
I think this battery will just fit with the space I have.

Have you ever paid attention to how your C6 burns off fuel? It burns the entire contents of the passenger side tank (9 gallons/55lbs) before it even touches the driver's side fuel. I wonder what that does to the balance of the car? How about a 240lb driver vs a 150lb guy?

I'd be willing to bet you could get away with one of these batteries in that smaller compartment. I'm thinking of trying one myself just for the weight savings.
It's half the size and weight, but provides the same power as the fullsize battery I currently have.

BTW, I've used the Odyssey and Deka (also known as Big Crank) batteries. Both are good. Deka and Braille are both made by East Penn. One is half the price.

The removal of a 35lb battery and installation of a 15lb battery is still a 20lb weight savings, regardless of what 12ft of battery cable weighs.
Moving the weight to the RR corner of the car is what helps with weight transfer and traction. You can try to rationalize your battery location/wire weight all you want, but it doesn't change the fact that it is always a benefit to move battery weight to the rear of the car.
I don't know why or how the "weight of the wiring" ever became an issue... but it doesn't surprise me that I've only ever read about that nonsense on this site. A gallon of gas weighs more than the length of battery cable I hung under my car... and I could certainly go on a diet and lose more lbs than that cable weighs.
I agree, the Deka batteries are good too... especially since I work for them.

I also own a Lotus Exige and moving the battery from the the rear to the front is the hot setup because you lose the heavy battery wiring. Again, I'm not drag racing.
I apologize if this has hijacked the thread. Let's get back on topic.

I swear I'm trying not to hijack, but a discussion of light batteries should include the company I use for my ZX-10R. I saved major weight and the battery requires no tending. It can sit for a year and still crank immediately. Absolutely the best battery I've had the pleasure of using. They also give you about a zillion high-quality foam adhesive-backed pads to customize the battery fit for your location.

Battery specifications are suspect between even the same battery badged differently. Some rate conservatively (Deka) and some optimistically (insert name here).
Another thing to consider is that by rerouting the battery to the rear you add significant resistance due to extended cabling. You need a little more oomph.
I don't think the Odyssey is any better when you consider the bang for buck. I'd probably (and did) go with the Deka. The Shorai is a bit pricier but IMHO is in a different (better) league.
I will say that the Odyssey and the Deka aren't quite the same once they become fully discharged. They just don't seem to recover fully. I honestly think you can say that about any battery.
