The AMS 08+ WRX/STI Small Battery Kit replaces your heavy factory battery with a lightweight race battery. This kit significantly reduces weight and frees up space. Our high quality components guarantee long life and the battery itself will have no trouble starting your vehicle in harsh conditions. The tray included is TIG welded by hand using high grade aluminum and the battery is topped off with a CNC'd AMS tie down plate. All factory mounting points are used making installation simple. While it can be used in cars with mild stereo upgrades it’s not ideal for high output stereo systems.
