I can't speak to the clues that you should look for that would indicate a new clutch is needed - I have replaced my clutch twice in 16 years of ownership (MY2001) and I am still at a loss as to what evidence is presented when driving the car to indicate the need. However, if your car has 83K on the odometer I would bet you need a new clutch or are at least very close.
The clutch engagement/disengagement point gets noticeably higher in the pedal travel as the clutch wears. And eventually it starts to slip, especially under heavy load. It is evident when the clutch needs replacing. For a street driven s2k that is not driven hard, it should be pretty easy to get over 100k on this car. If doing stuff like autox where you may launch the car harder sometimes but not drag racing (constant hard launches) you will likely see shorter life and if drag racing it will get shorter from there. On most manual transmission cars you can expect to see even longer life, but we drive a relatively torqueless car and thus more clutch slipping to get a smooth takeoff. Stop and go traffic will cause a lot more wear in this area.

I bet a lot of clutches on this car get replaced unnecessarily.

Most of the clutch symptoms people report are due to the clutch not fully disengaging (the opposite of worn clutch), not a worn, slipping clutch. This cars clutch is very sensitive to clutch fluid condition and trapped air, and adjustment. It also doesn't like aftermarket clutches. These fail early, but almost never wear out, because they fail mechanically before that can ever happen (they drop a spring, car become undrivable because clutch can't be disengaged at all.)

When clutch starts acting up, they bring it to a shop, who wants to replace the clutch instead of actually diagnosing the issue. Then if an aftermarket clutch is used, the clutch will fail for real long before the original woukd have if only the real issue had been addressed by tbe shop.

Its not entirely the shops fault if they aren't familiar with this cars unique clutch concerns.

There is someone in this forum that has over 300k miles on his original clutch. Yes, dang. Not saying they can all last that long, but it bolsters notion that perfectly fine clutches are being replaced by people rhat don't know how to properly diagnose and correct this cars clutch issues.

Do a proper gravity bleed until all fresh fluid. If it was really dirry bleed it again in about a month of use (fresh fluid will continue to was built up residue off piston, etc.)

Adjust clutch rod (watch excellent diy youtube video)

Check clutch pedal height adjustment

If someone replaced oem clutch woth aftermarket, may bot be possible to get clutch working properly until a proper Honda oem clutch is installed. Note, Exedy OEM is NOT the oem clutch. Just a marketing gimick.

I honestly think many make this more "special" than it really is. It is a hydraulic clutch. Bleed it properly like any other and it will keep working fine. Have never had issues of having to bleed it again unless I did something to warrant it. Have never touched the clutch adjustment in the 50,000 miles I have owned it and find it engages at the right spot. Choosing the right parts is key but otherwise it is a pretty reliable and easy system to work on. I would say any capable shop should be able to diagnose and work on it just fine. Many shops nowadays just like to be parts replacers instead of actually digging in to find the issue and that is more of a shop issue not some special thing about the S2k. I also think that as it wears, some start fiddling with the adjustment and get it in a bad place, leading to them thinking there are other issues.

Well, I do have to admit mine has been very trouble free & maintenance free since I replaced the crappy aftermarket clutch the car came with back to all Honda parts (with act pp & streetlite flywheel), and grwased everything properly. I just do a mc fluid swap every other oil change. Adjusted clutch rod maybe once.

But man was the thing finicky when it had the aftermarket junk from the PPO (original owner, I got it from second owner). The car only had 67k miles when I got it. I can't imagine the original owner wore the clutch out that quickly (replacement had to have been even lower miles than that, as owner I got it from bought in FL, drove to upstate NY, and drove it around for a year.)

So original clutch replaced (probably) unnecessarily, then aftermarket clutch never worked right. Eventually failed like they all do (dropped spring).

No amount of adjusting clutch rod or pedal height or clutch fluid or greasing shifter or fresh fluid or polishing/ greasing fork knob would get the aftermarket clutch to work right. It was probably due to grease, wrong type, wrong amount, wrong places.

So a shop that is too lazy to diagnose the clutch issue is likely to also be too lazy to read tbe service manual, obtain the correct grease, and apply it properly. So new clutch, even a crappy aftermarket one, will 'fix' the issues, for a little while. But then soon it'll start acting up again, as the wrong grease missing from the right places will catch up to you.

Bottom line:

Don't replace clutch unless its actually slipping or dropped a spring

If its not shifting right, diagnose and address the actual issues

If you do need to replace the clutch, make sure to either diy (and follow service manual and use Honda urea grease and Honda parts), or find a shop that has experience and success doing clutch on this car. Barring that, a shop willing to follow service manual and use the proper grease and proper parts.

Yeah I think most peoples issues stem from using some sort of aftermarket thing and then trying to "Adjust" around it to make it better as you say

I'm not really sure why anyone feels the clutch needs periodic adjustment.

Its adjusted from the factory.

The pedal engagement should stay the same until the clutch has worn past its workable limit.

You shouldn't be adjusting for wear.

Like...you wouldn't top off brake fluid to account for pad wear.
I hope....

This seems ridiculous to me. Afaik my 156k mile AP1 is still on the original clutch and things still feel ‘right.’

Ask Billman to check it out when he has the car and follow his advice. He puts clutches in very quickly. Not a huge job for him at all. And, it will be done right. Personally, if I went to the trouble of getting my car to Billman with the mileage you have - I might just do the clutch even if it has life left. These cars are getting old and stuff starts to dry out and stick etc. But, bottom line is I would follow Billman's advice.

Yea... I've had an AP1 and an AP2, both right around 110k miles. I owned each for 2+ years and launched them probably 80+ times a year. Both were on the original clutch. Another guy I knew that autocrossed had his last to 180k+ before replacement. WTF are people doing to melt a clutch pre 80k?

I did have a shop tell me that mine felt weird. That shop was very familiar with S2000's as well and I will probably go to them to replace my clutch when the time comes. He may have been right but that was 15k+ miles ago.

It is the failed launches mostly I think. Some really are scared to launch hard enough to get some tire slip, especially on sticky 255's. So they try to slip the clutch some and end up just smoking it off the line. I have seen S2k's launch at events, likely thinking they were spinning tires, when they were really just smoking the hell out of the clutch lol. I replaced mine at around 120k I think but given it was an autox car for a couple of others before me, I assume it had some of the same.
