The AMS 04-07 WRX/STI Small Battery Kit replaces the heavy factory battery and mount with a lightweight race battery mounted on its side. Weighing in at 15lbs. our kit not only reduces weight but its design lowers the vehicle’s center of gravity as well. We utilized all factory mounting points making installation painless. Our high quality components guarantee long life and the battery itself will have no trouble starting your vehicle in harsh conditions. While we do not recommend use with high output stereo systems it can be used with mild stereo upgrades.
