Which battery relocation kit?

Moroso makes a blue one that is actually plastic and is still track legal. The box with hold downs and everything but wiring is like 100 bucks and then if you order their wiring kit it's like 95 more. This is the kit I have right now, but I'm not using their wiring kit.
 

I agree and that summit box is the same thing as the blue moroso boxes... tons of people run them so they can't be bad
