or you could just be lazy/awesome and get a lightweight battery I had to pull my intercooler pipes for the POS mopar battery my car came with, and an optima red top wouldnt even fit at all so I picked up an Odyssey lightweight racing battery:


And then picked up an AMS Tiedown kit...so it kinda sits like this (AMS Mockup):

I figured the engine is flat so the motor should be too
Ba dum...
