Best way to relocate battery?

I need to relocate my battery. I have jury-rigged the original battery tray beyond recognition and it can no longer hold the battery. Who has relocated their battery in a hatch, and what kits/methods have you found work best? My car gets raced often and the battery must be secured properly. Thanks.

Cash, gas, ... or .... No one rides for free.

Take a ride on the smokey side...

First: '89 LX hatch Red, sold at over 190K
Second: '89 LX hatch Red, lived in then repoed.
Third: '87 GT hatch white, blown transmission.
Fourth(Current): '93 LX hatch, 46K w/crap paint.

I used a kit from summit. http://www.summitracing.com/parts/sum-g1231-k/overview/ it was a little work. Pulled interior to route cables, had to crimp/solder those huge connectors on the ends. I can't remember but I may have had to drop the tank to drill the holes in the trunk and access the bolts on the underside. Don't forget if you want to go to the track you need an external kill switch.

You can save yourself some possible future electrical issues/problems by running a black ground (negative) wire up to the engine bay with the red positive wire and connect it to the engine block and anything else (ground wires) originally connected to battery negative.Computer equipped cars sometimes do not react well using the body to reference negative ground to the ecm and sensors rather than direct wiring.I sometimes wonder why the battery kits offered by suppliers dont offer an optional(extra cost) full length negative cable to match the positive cable.Using the body to flow current back to battery negative is not the best of ideas.

I've trunk mounted the battery both ways. It works both ways, but I do prefer to run a ground from the battery to the engine.

Vehicles with frame rails seem to be able to handle current flow much better than unibody cars as long as connections are good.With computer controls requiring (0-5 volt) low voltage signals along with ground reference signals to computer can fluctuate trying to flow through all the spot welds on body back to battery negative.Never was a problem before computers but todays vehicles are a different story.
