So, I was at the OCC All-Mazda Meet yesterday - and stumbled upon GT-Spec's booth. I walked away with one of their GORGEOUS strut bars for my 2012 3s hatch.
I recently bought speed springs from @swerv0428 and decided today was a perfect day to install those, and my newly purchased bar. My mazda6 buddy, pointed out that when I have the strut bar on, I can't get into the battery box, and just last night after seeing Iron Man 3, I jumped some guy's Neon in the parking lot - my jumper cables get a lot of use. So he had the great idea to make something outside of the box, so I can have my strut bar and use my battery terminals. I bought a few items from Advance Auto Parts, and Lowe's.
-Autocraft 10" Top Post Terminal Battery Cable
-AutoCraft Long OEM Bolt
-Dorman Copper ring plug 3/8 2 gauge
-stainless steel 3/8 washers
-stainless steel 3/8 locking nuts
-3/8 drill bit (I didn't have one sadly)
First thing I did was snip off the terminal end of the new cable:
then cleaned it up:
then added the ring plug and crimped it on:
mocked up the other end: (ended having to use 5 washers in total)
next, on to drilling. I used a per-existing hole in the front of the battery box:
and just made it a little bigger:
Installation:
and the other end:
finished product:
All in all, this took me about twenty minutes to do. Easy and quick.
