Focus RS Battery Holder
"This is a brilliant bit of kit, and a must for any RS owner, great weight saving."

Lightweight Batteries are an excellent and inexpensive way to remove weight from your Ford Focus, which has an OEM battery tipping the scales at 44lbs. The GrimmSpeed Lightweight Battery Kit shaves 30lbs or so from the factory system and is a simple, straight-forward installation with no cutting/drilling required and an OEM look and feel.

"Super easy to install. Couldn't believe the fast shipping. Ordered 10am few hours later it was being shipped out! Great and cost affective weight reduction. Haven't had any issues."
"When I saw an online install video that noted the install of the Grimmspeed PC680 would take 47 lbs off the driver's side front, it was a given I'd have to install the battery and mount. Install was very easy but I found that the battery moved around enough that it wouldn't pass a tech inspection. I purchased some foam tape and applied it to the bracket in spots that it would come into contact with the battery, problem solved."
