The STM 680 small battery kit for 2015-2021 WRX/STi allows you to install a smaller, lighter battery to save 18 pounds while lowering the center of gravity. This kit fits cleanly in the stock location and installs in minutes with the new tie-down hardware. Includes a non-slip pad to keep the battery snug and reduce shock while driving.
The battery tie-down kit is available with or without the Odyssey PC680. Battery purchase will include a set of new terminals. Please note we cannot ship batteries outside the continental USA.
