6 You can simply yank the rear seat out of the car, but that leaves an ugly interior. The Razor's Edge rear-seat delete kit comes with both a lower panel and one to replace the rear seatback. Both panels are nicely upholstered, matching the factory carpet and interior perfectly. We were surprised how much our car's factory leather covered rear seats weighed, right at 10 pounds for the seat, and another 40 pounds for the split, folddown seatback. The combined weight of the Razor's Edge rear seat delete panels is less than 20 pounds, resulting in a substantial weight savings.
