Lightweight Battery Installed

In an effort to reduce the weight of the M3, I’ve installed a Russ Wiles battery box from BimmerHaus along with a Hawker Odyssey battery. The battery box is designed to hold this small battery and be mounted in the stock location using factory cables and hold down clamp.

The stock battery weighted 43 lbs. The new battery box + battery weighs 18 lbs.
