PowerLabs' Battery Relocation!
I won't do a write up here, but I have one if anybody wants, just PM me for a link.
For this install I studied the way the battery is installed and cables are run on a stock C6Z06, and replicated everything... It came out pretty nice:
21lbs absorbed matt battery tied down with a lightweight backet:
Cable Run on stock location:
Fabricated new harness with wire loom and heat wrap:

I'd have to guess that it would be to help restore the weight balance of the car. He has a blower system that has to add some weight over the nose.

Guys with S/C's can set the balance back to stock. The S/C added weight up front and the battery relocation corrects the weight balance and can actually get rid of some of the weight with a lighter battery. I used a D35 optima which is 10 lbs lighter.

I have both sets of cables active so i can run it in either location. The ground was made to the frame in the back so there is no need to make a ground up front. The red power line gets connected to the front.
I wanted the space to be available for a stand alone nitrous fuel system that mounts where the front battery location would be.

Any idea of how much weight the longer cables added back in (even with that gain factored in it's obviously still a nice weight loss overall as the battery itself is much lighter than stock 
)?
)?

I did this for the same reason I run race tires
And have a supercharger
And a ZR1 cam
And race pads
And Methanol Injection
PERFORMANCE
I removed 23 pounds from the car overall, and did that by adding 21 pounds over the rear tires where it helps traction, while removing 46 from the front of a car that is already somewhat nose heavy from the factory. The Z06, the ZR1 and the GrandSport all have their batteries in the back for that same reason: better weight distribution, more traction and a cooler environment for the battery where it lasts longer.

It is mostly about removing that 44lbs battery (and another 4lbs from the harness and tray) from the nose of the car. This is specially important to me because I have a supercharger up there and need neutral weight balance for autocross and road race events.

I've got a similar set-up with the Optima D34 Yellow Top in the rear and room for a meth set-up in front.

I did it for traction alone. Taking 43 lbs off the front of the car and putting 32 lbs over the rear tire really made a difference in my cars ability to get it to the ground. Anyone spinning the tires will gain from this mod. It gains because of the weight on the tire and weight transfer.

I kept my stock harness too so I could go back to a front battery if I wanted to.
I grounded my battery to the frame on the back too, but I ran an additional ground between the engine and the frame to prevent ground loops through the drivetrain; not a concern if you kept your stock wires, but definitely one if you remove them...

very nice,, ive been wanting to do this for a while now, but ive heard if you relocate you need a battery cut off at the drag strip,, i guess i could just tell them it comes like that from the factory. hmmm
like what you did with the ground wire,, you can NEVER have enough grounds.

And lately some Toyota Camrys have even been doubling that speed limit whether their owners liked it or not LOL. 
5.6 pounds evenly distributed from the front to the back of the car.
