My XKR is pretty quiet as it is, but I've got this thing about doors that make an expensive sounding thwump when I close them and I was thinking about adding some Dynamat. Problem is I haven't been able to find any pictures of what's under the doorcard, or how easy a job it would be. Anyone done this in their XK8/R?

 

There is a thread with pics in the FAQ list in the xk8/xkr subforum. The rattling is from at least one dislodged glass guide/bumper. I found one of mine in the bottom of the door. I used some loop tape (from velcro) to stabilize it where it needed it inside the door before finding the bumper. Works well.
