Thank you. You have rated this product.

Yes, we have seen what they are doing in Japan, charging as much for the mount as the battery costs, and all for only 200 Cold Cranking Amps. We think you should be able to park your car for the weekend, even a holiday THREE DAY weekend, and still have it start the next week! Thus, we are going a bit bigger, without really going any heavier. And why not, you got the space! This is a Battery Tender ultra light LiFePO4 (Lithium Iron Phosphate) battery (DELTRAN BTL24A360C), and as you can see on the label 360 CCA and the mounting setup and battery together just 3.35 Pounds! We will not be selling the battery, they are available from dozens of places on Ebay and Amazon. We will be selling just the aluminum mounting kit. This is for RACERS ONLY, we don't see much point for regular street customers, but for SCCA autocross customers we think this will prove the popular setup. Saves 23.4 pounds off the front of the ND!!!

What you get:
- Lightweight aluminum brackets to hold the battery securely in the factory location
- Stainless steel battery cable adapter
- Hardware included

Below is STOCK battery and all hardware that are removed, total 26.7 pounds.

Below is what you add back, total 3.35 pounds, weight savings 23.4 pounds!

- The battery this kit is designed for ships with adhesive-backed foam padding in various thicknesses. Apply the 1/4" thick pads to the battery brackets in five locations; on the two vertical ears on the main base plate, and on the two sides and the top of the straps that hold the battery in place.
- To install the cable adapter on the positive terminal, first unbolt the round battery post connector from the fuse junction on the positive cable and then replace that post connector with the supplied stainless steel adapter using the included 8mm hardware. The adapter attaches the cable to the battery at an angle so that the standard cable length does not need to be changed. See photo at the top of this page for reference. To fit the plastic post cover over the positive terminal again, just trim the side of the cover with a razor blade to clear. The negative cable can be bolted right to the battery without any changes. Again, see photo for reference.

Brian's Extra Notes: So far we have had zero issues with the 360 CCA battery choice used in our ND, but it is very interesting to note that Battery Tender offers a 'bigger' 480 CCA that is in the same size case, the BTL35A480C. Weight climbs from 2.6 for the battery to 3.75 but for those needing more extreme duty an interesting additional choice that works exactly the same in our bracket setup! Note Battery Tender makes a special little charger for these LiPo batteries because an old standard lead acid charger can wreck these lithium batteries. Numerous other choices will fit, bracket takes batteries such as AntiGravity YTX12-24, EarthX LTX900 and LTX1200 (the last two are TALLER and need spacer and/or longer bolts not included with bracket but worth the trouble for those seeking even more power...600 CCA for the LTX1200). Research the specs of these so you can pick the choice right for your use.

I just installed the Borla exhaust on the MX5. Sweeeeeeet! Thanks, Andy


After reading many other positive reviews on both the GWR and Miata forums I finally decided to buy this product. My main concern for many months was whether or not I was up to the task of installing the header. But with the excellent instructions on Brian's forum as well as several Miata forum threads it turned out easier than I expected. After receiving notice that the header would arrive on a Friday afternoon, I began the disassembly process. After about 3 hours I had the stock manifold out. Later that afternoon the new catted header arrived right on schedule. And it is a thing of beauty. I opted for the stainless version. Installation on Saturday morning took another 3 hours, although I could have shaved some time off of that but I was actually enjoying the process of double checking torque values and cleaning up my engine compartment. I already have the GWR catted midpipe, so that connection was a snap. I put everything back together, reconnected my battery, and went for a drive. NO CODES! Nice throaty sound with my RSII muffler, and a significant boost in power and low/mid torque. Another happy camper here. I since have added a M-E tune and I feel I have realized all of the gains that Brian has achieved on his 2012 project Miata. I've put several hundred miles on my Miata since the install with zero problems. This is the car that Mazda should have built all along. Thanks Brian.
