Default Is this ACT clutch disk worn?

I'm in the process of replacing my engine and am doing as much preventative maintenance while I'm in there as I can. However, I want to be smart about where I put my funds and not replace anything that still has significant usable life.

My clutch is an ACT with the heavy duty pressure plate and organic clutch disk. While it is over four years old, it has just 10k miles. Those 10k miles were 90% on the track though, so keep that in mind. The clutch works great and I have had no issue, but if it getting close to the end of its useful life I'd rather replace it now rather than later.

Anybody here have expertise they can share? Judging from the pictures below, what % of the clutch life remains? A new disk is just a little over $100, just does it even make sense to replace that without replacing the pressure plate? Not sure which one typically fails first.

Smart to replace the pilot and throw out bearings while I'm in there too? They are also 4 years/10k miles old.

I feel like track would be less abuse on a clutch compared to stop and go city driving daily commuting constantly engaging and slipping.

Gotta love ACT clutches. I had the same setup on my AE86 that saw countless auto-x's, daily driving, drift events, tracks days, you name it. Its been in the car over 10 years now is still working fine according to the new owner.

Oh, there's that Goodwin clutch too. If I didn't feel cheated over the exhaust I'd probably buy one.

I put in an ACT from FM in 2002, when that was what they included in the happy meal sets. 10 years and 55K miles later I took the motor out to build it, and the clutch barely looked worn, so I put it back in with the new motor.
