STM Small Battery Kit for Evo 5/6

The STM lightweight small battery kit for Evo 5/6 allows you to drop 21 pounds vs the factory battery, lightens up the front of the car and clears room in the engine bay for new intercooler piping.
Newly redesigned in December 2024, the STM tray is now machined in-house from billet aluminum. Includes stainless hardware and mounts to existing points in the chassis for an easy install.
The battery tray is available with or without the Odyssey PC680. Battery purchase will include a set of new SAE US terminals. Please note we cannot ship batteries outside the continental USA.
Vehicle Fitment:
Mitsubishi Lancer Evolution V VI
• Fits Evo 5/6 – NOT Evo 4
• We include SAE US sized battery terminals if you purchase the whole kit. Some Japanese models may have a JIS terminal size and that will not fit. You’ll have to source a JIS terminal locally that will work with your car.
• This is not a direct fit for Evo 4, the chassis bolt hole is just a bit off.
