Do It Yourself: Yes
This is more towards aesthetics mod. Considered as revision 2 of original mod to overcome wind and noise intrusion between the two doors at the center pillar.
This mod consist of two sections for one door (top to bottom). I will start with the bottom section first.
This was the original mod. Using a simple rubber seal and running along the front door. It did the job marvelously but it does have one issue as the image below…
Next the top part of the door frame. For this mod, I use parts from Citroen Xsara Picasso.
