JBR 51R Small Battery Tray for the Mazdaspeed 3


    Now that spring weather is on the way, I am able to get back into the garage and start working on projects again! My battery died over the winter and I needed a replacement, so I decided to swap it out for a smaller group 51R battery and a battery box from James Barone Racing. Now fitting a larger intake will be easier!
