My question about battery relocation is can you relocate it to the rear, and hold it down with L-brackets? It doesn't seem like the battery box would stay in one place when taking all those turns at those speeds. I am going to be using "L" brackets bolted to the cardboard in the trunk to hold the sealed battery box down, that should be ok right? Most people drill the box into that cardboard, but doesn't that defeat the purpose of a sealed box.

And I plan to use a high-rated fuse, probably 250 amps (I know the starter pulls a lot more, but this is the highest rated fuse I can find). Will I have to get a main power switch, so if anything, that one switch cuts off all power to the car?

 

I wouldnt bolt a battery the cardboard. I would throw it in a bix and bolt the box right to the trunk floor.
