2008-2019 WRX/STI Lightweight Battery Mount Kit by GrimmSpeed

GrimmSpeed has always been on the forefront of innovation when it comes to well-engineered functional parts for your vehicle. When we introduced a lightweight battery option for Ford Focus RS owners, they had nothing but good things to say.

Now we are bringing that same innovation and forward-thinking to our Subaru enthusiasts. Introducing the Lightweight Battery Mount Kit for the 08-14 and 15+ Subaru WRX and STI.

Lightweight Batteries are an excellent and inexpensive way to remove weight from your Subaru, which has an OEM battery tipping the scales at 34lbs. The GrimmSpeed Subaru Lightweight Battery Kit shaves 19lbs from the front of your vehicle and is a simple, straight-forward install with no cutting/drilling required. The lightweight battery tray design features 3 mounting points that will securely hold the tray and the battery. If you race in SCCA AutoX you should have no problem passing tech with this setup!


  • Laser cut, CNC bent aluminum bracket
  • Durable red texture powdercoat
  • Utilizes Odyssey PC680 Battery (or anything of similar size)
  • Knocks off 55% of weight as compared to OEM Battery
  • Easy install and removal
  • Will work with the GrimmSpeed Billet Aluminum Tiedown
  • Will work with the metal case for the Odyssey PC680

Please Note: The GrimmSpeed Subaru Lightweight Battery Mount Kit was designed to be used with the Odyssey PC680 Lightweight Battery, but should be able to be used with other batteries that share the same dimensions. Before purchasing, be sure to measure your specific battery to make sure it will fit as intended.
