Anyone who's been around Miatas knows that the battery only belongs in one place: the trunk. Mazda forgot this in 2006 with the NC, and forgot it again with the ND redesign. Well, we've accepted it for too long and now we're taking action.
What's the big deal? The battery is one of the densest chunks of mass in the entire car. A stock unit is around 25 lbs. Putting it over the front wheels adds to front weight and also eats up valuable real estate. Moving it to the trunk makes an immediate difference in your weight distribution.
Yes, we know that the current fashion is to use a featherweight lithium battery. These require special care and have...disturbing failure modes. That also doesn't solve the problem of underhood space.
This kit was developed for our V8 conversions, where both distribution and underhood space are important. It puts the battery in a little cavity on the driver's side of the trunk where it's out of the way but easy to access. There's a kill switch just above it which is very convenient for storing or working on your car.
We also add a jump point under the hood. This makes it easy to jump the car or charge the battery. It also means that if your battery is dead and the electric trunk release isn't working, you can still get power into the car! That's a pretty important detail.
Includes a Sparco battery switch, a 350A fuse and fuse holder, a kill switch bracket, and all of the wiring (4ga) and hardware needed to move the battery and mount the various bits other than the battery bracket itself. We recommend using an Odyssey PC925T and the matching Odyssey bracket, available all over the place.
Please note that this doesn't currently have instructions available and is intended for our V8 conversions. It will work with a four-cylinder, but will require a bit of problem-solving.
Designed for the ND, but very compatible with the Fiat 124.
