I've noticed that every MK3 I've been in has the same issue. The doors don't feel solid when they close. I wonder if there's something we can do to make the doors feel more solid, like the MKIV and maybe even S2000.

Thanks guys

The doors themselves are quite solid, but I know what you mean. It makes a hollow "bung" type sound or the regulator and rods rattle when you close it.

If it really concerns you, take the door panel out, take your sockets and go crazy. You'd be surprised as to how many loose bolts you find in there, and there's some stuff you'll have to adjust back to spec. There's probably a few broken lock rod guides in there. New felt window guides do help as well.

These cars ARE like 20 years old, remember ;)

Yea, it has that hollow type sound. Is that the only cause? Loose bolts inside the door?

It's a start. It'll mostly fix the rattles, but I noticed a pretty noticeable difference when I did it to my car however many years ago. Car had 180k on it and there were a few bolts that were backed out.

There's probably some type of foam you can put in there to give it a more solid sound.
I just deal with it now lol

I have the full door matted (2mm) inside with (same stuff like Dynamat), plus one more soundisolation foam just behind the door panel. Sound feels quite different in comparison with a stock door, I think more ''solid'' as you call it.
Now I just have to get the windows tight (new felt) and it'll be perfect I guess.

Yea, I had no idea it would have to do with the inside of the door itself. I thought it would have to do with the way that the door is attached to the car. Also, my hinges make kind of a click at half way.

That's the door stopper clicking. The 3rd ''hinge'' in the middle with the handle that moves.
At least I think so.

Is it supposed to click? I've tried some WD-40 with no luck.

Don't forget to look at the door's hinge pins. On a 20 year old car, I could almost guarantee that they're worn an need replaced.

If they're worn, they'll let the door drop slightly when it opens; and it'll defiantly make more noise when you close it. On my car, the passenger door closes like a new car; but my driver's door drops a slight amount when I open it, and makes noise when I close it. Once I replace the hinge pin on my driver's door, it'll close like new again.

Where exactly is this "pin" located and how do you replace it?

Well there is the middle position where it holds the door, so if you open it fully, it has to overcome this middle bump... and it clicks :)

I think he means the small pins between the two parts of the hinge (one on the door, second on the body) that holds both together?

New door hinges, new door check, new glass runs, make sure none of the rods are loose/able to rattle, new weatherstripping.

Once you replace all of these things and make sure nothing can rattle in there by replacing the foam pieces, etc, then your doors should sound pretty good when they close.

On my new project car, a 100k mile 86.5 chassis, the doors sound fantastic when they close. It's a nice, crisp closure. When sitting in the car, you can feel the cabin pressure change, and it makes a nice thud. I can push them closed with my pinky finger and it's the same.

My old black car, which had 180+k on it- not so much. Didn't feel good, or sound good at all.

As for me and my 172k mile old supra, I took out the parts/mechanism inside the door, and sprayed some rubberized undercoating for sound insulation and then I replaced the door weatherstripping, I am currently in the state of replacing my window regulator since it is bent, along with the other bushings and guides. Other than that when I finished my passenger door, it shuts perfectly, im still workin on the driver side BTW
