Just had the new slave cylinder installed, such an improvement!
Thanks OP.

When we did @Jonesy86's last Tuesday I was amazed at how long it took to work out all the air. Definitely more than a few cycles but his clutch fluid looked contaminated. There may have been something else going on with his. I'll be checking it again this weekend.
I just did mine quickly (as it starting snowing ) and my fluid definitely looked off. How did his fluid look? Mine looked like it had black particles in it, which I have to assume is not normal. As it is snowing pretty good I haven't gotten a chance to drive it much yet, but it does feel much improved. I'm wondering if I should try to flush the system however.

When I started this, both my brake and clutch reservoirs were the same slightly golden color. There was a tiny bit of shmutz on the bottom that I stirred up when I first poured to top off. It was nothing like the black I see now after a couple months.

Still, the fluid color and small black particles are no worse than any slave cylinder I've serviced/owned. It's just not squeaky clean new like my original brake fluid still appears even after 10 Kmi.

I attributed the change in color to the brand of fluid I used. Was yours factory? What does it look like in comparison to your brake reservoir?

Thumbs up

So I have had the new slave installed for about 5 days now, and have done a mix of driving in some stop and go traffic, street driving, and highway driving. Currently I am running without the pedal helper spring, the pedal adjusted to even with the brake pedal, and a bumper behind the pedal to limit throw. I also have the TRD short shifter installed, but that really shouldn't have any effect on the feel of the pedal, just shifting overall.

My impression is that the smaller slave cylinder has certainly helped with pedal feel, and the travel feels much more uniform and linear. The engagement point is definitely more apparent than on the stock car, or than with the helper spring removed. The pedal is stiffer, but not extremely so. I haven't really adjusted my shifting at all, but the car does shift smoother (or I'm imagining it). However, I am not quite as staggered as other people have been. Maybe it's the fact that I do not have the helper spring, or that I have unrealistic expectations, but it's still not quite what I expect a clutch to feel like. I can certainly feel the engagement point better, but not quite as much as I would've liked. This could be because I'm shit at shifting and wore my clutch out (I don't think so, you might), wear thick combat boots while driving (more of a running shoe guy), or am never happy (quite likely).

This is not to say I think it wasn't worthwhile, it definitely is if you are looking for better feel. I even like how stiff the pedal is, and I don't even feel like it is bothersome in heavy traffic. The prices for the parts direct from Subaru are cheap enough, and the work to install it easy and quick enough that I think everyone who thinks they have a problem shifting should try it. Easy enough to switch back if you go FI, don't like it, or whatever. Also, in my case, it was just something enough to scratch the mod itch for a short while without bankrupting me

TL;DR - give it a shot.

I keep forgetting to pop my hood and look when I'm getting in and out of my car. My fluid isn't really a different color than normal brake fluid, just had some black... dust? for lack of a better word. I'm not really too concerned right now, because even when actuating the clutch, it didn't really get stirred up. I only noticed it when I poured the new fluid in to top it off. I figure if it's settled in the reservoir, I'm probably OK for now. I will try to get a look at my brake fluid to compare them though.

You don't have unrealistic expectations. This clutch is weird for sure. Whether it's the way the clutch fork pivots or if it's the design of the pressure plate, it's really goofy. I'm used to clutches biting a lot harder much earlier in the lift. This one doesn't grab hard until almost the end of the pedal throw.

Maybe eventually I'll drop the tranny and dig around.

I think I agree with @Cuchullain. I had the smaller slave cylinder on for about a month with the helper spring removed and it was definitely stiffer (expected) with very minimal (if any) increase in feel (realized after the honeymoon mod period). I think the removed helper spring with the added stiffness dampens an extra feel you may get with this slave cylinder install.

The smaller cylinder should reduce the range of the pedal from first initial touch to full engagement so you'd have to be more precise with footwork and the negligible increase in feel actually makes it harder to drive smooth.

The amount of people providing positive responses towards this modification leads to me believing that this is most effective with the helper spring installed. Is that a fair conclusion?

I drove my mates evo 7 and the pedal was so vague but there was so little effort required to get seamless shifts. It felt so natural. Maybe our newer clutches are more grabby

I remain thrilled with how much the feel has improved. I quit accidentally smoking the clutch and that hasn't changed.

Mmmm... personal preference, I guess. I hate it.

I'd like to hear other's opinions. Any input I have can reasonably be discounted due to perceived bias. I'm ok with that. Tear it up.

Had a chance to drive @Ultramaroon 's car today, This makes the car feel like it has an actual clutch. The stock clutch by comparison, feels kinda like stepping on an overripe grapefruit connected to a random number generator which determines when the clutch will grab.
