You probably already tried this, but: Have you made sure the stainless steal trim over the sill (where the seal sits in), is mounted al the way inwards? Mine weren't, after fixing that the door shut a lot better with the new rubber.Pete. Can you expand a little bit on "modifying your doors" to get them to shut better with the rubber stripping in there? I'm going through this right now on my car and finding that at the bottom of the driver's side door it is just a touch to tight, and therefore pushing the bottom lip of the door out of alignment with the sill. Argh. Thanks.
