    While every pound counts, 6.5lbs in the grand scheme of the car isn't very much. You are also taking the cable and battery from one of the lowest points of the car and placing the battery a few feet higher on the battery shelf in the bay. Probably best to go to a lighter battery but keep it in the stock location.

      Yes, you'd better be buff, slender, and have drilled lightening holes in everything you
      can get to, including your butt,

      but less weight in a sedan= lower lap times.

          A solid choice backed up by decades of precedent.
          Your corner weights will thank you.
