2002-2007 WRX/STI 900 Series Battery Mount

Great looking piece! I was able to make it fit without modifying the existing battery location. I did end up drilling out one of the mounting holes on the battery box a little wider to get it to be able bolt up.

I also installed the threaded backing plates I believe upside down (u shaped portion facing down) to be able to get the provided hardware to reach the threaded holes.

I had the 600 series prior and loved the added space in the engine bay I gained. With the added space I added the fuse and relay box for my auxiliary rally lights and other functions. The 600 series was wonderful but having the added capacity while retaining the small form factor, the 900 series is so worth it!!! Everytime I get teched at an Autocross or Rallycross, the inspectors remark about how sturdy the battery is secured, and it's the truth!

I bought the 900 mount to fit my build and living in the PNW! I had a couple questions about battery availability and Mitch was fast to respond and got me the product with plenty of time to spare on a deadline I had for a trip. The mount is easy to install, and measuring carefully I was able to mount in the factory location. If you have a front mount kit with a relocated coolant reservoir you will want to mount it as far back against the engine wire harness mount as you can but there is plenty of room and you could also angle it some if needed for different positioning needs. Installation was quick, easy to do and is extremely solid. The welds are amazing and this thing is built to last. If you have a bigger build or live in colder climates the 900 series is a good option to save a little weight but not have to constantly worry about the battery charge like in some smaller battery applications. <3 Mele for the great product, customer service and quick order fulfillment!
