GrimmSpeed Lightweight Battery Mount Kit

Backorder until mid to late January

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, straightforward 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!
