The next step was to "add lightness" as Sir Colin Chapman once coined.
I've actually been weighing the parts as they went in and out, see below. My starting point was 3120 lbs with a full tank of gas. As of today I calculate that I am at 3043 lbs. I ended up reinstalling the trunk carpets minus the rear sound deadening after my wife freaked out
, and reinstalled the carpet above the engine cover because the high pitched belt whine was really annoying.
