It's just at that price, it seems too good to be true...
Well I found the battery at Amazon and according to the description, it's to power an audio system...not what I intended to use it for

Needswings sells the same battery as a kit to fit the Xfires. It includes the SAE top post adapters and a custom made battery tie down spacer for around $90, which is very reasonable. I went this route looking to cut weight on the popular belief that every pound shed gains you 1 HP. My car is my daily driver back & forth to work, so it works fine for me. Had it installed since last Nov. and not a lick of problems. There are a few other members who use the same setup.

Another cool thing being done is mounting the battery behind the passenger seat, freeing up the battery tray area for NOX or intercooler installs.
