The Perfect Upgrade For The Weight Conscious Enthusiast: 

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!

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.

Odyssey PC680 Battery

GrimmSpeed has partnered with Odyssey to bring you the best deal on the PC680 Extreme Series Lightweight Battery Cell. This battery pairs perfectly with our mounting kit and can be included for an additional cost.

The ODYSSEY battery can handle it! Featuring rugged construction and packed tightly with pure lead plates, the non-spillable AGM-design ODYSSEY battery protects against the shock and vibration that can quickly destroy other batteries. The pure lead plates mean more power; twice the overall power and three times the life of conventional batteries, up to 400 cycles at 80% depth of discharge! In fact, ODYSSEY batteries are capable of providing engine cranking pulses in excess of 2250 amps for 5 seconds – double/triple that of equally-sized conventional batteries, even at very low temperatures.

Disclaimer: Odyssey recommends using a metal battery shield with the PC680 for high-temp applications, warranty claims may be affected by not using one. The GrimmSpeed Tray fits the PC680 with or without the metal shield.

Awesome style and versatility

Great style and super lightweight. Yes, it does fit the 2019 Subaru Impreza sport sedan and hatch. Not a fan of the hex screws as it is difficult to remove after install or changing batteries. But overall, a must have if you’re planning on upgrading your turbo or customizing a turbo setup.

Light weight odyssey battery and tray.

I bought this battery kit for my 05 legacy gt. It is a direct fit for the legacy except minus of using the one bolt on the bottom tray. It makes the engine bay look cleaner and gives me alot more room for the front mount intercooler pipe.
