Slave, clutch, and flywheel

Slave, clutch, and flywheel
So I’m almost positive my Slave Cylinder is shot, so I definitely need to replace that. Because of labor costs, I figure I might as well bite the bullet and do the clutch and flywheel while the tranny is dropped (I have no clue the last time these were changed, or if it they ever were changed). The car has about 52K miles on it right now. Here are my questions; I would appreciate any input from people who changed out these parts:
Slave Cylinder- I’ve done a lot of reading and it’s pretty apparent the current CSC is just bad because of the shotty materials used for it. I don’t really want to get an OEM because I don’t want to run the risk of it going bad all the time. I am thinking about buying the aftermarket one seen here https://www.myg37.com/forums/engine-...-08-coupe.html To the people who have used this… It says some modifications are needed to put this in… was this a PITA, or should a mechanic be able to do this no problem? Also, will this need to be replaced every clutch job, or should it last a pretty decent amount of time?
Flywheel- Again, I’ve done a lot of research, and obviously the OEM flywheel cannot be resurfaced, so I will need a new one. The big question here is to go OEM, or aftermarket? My dilemma is this… I HATE when my car makes noises it’s not supposed to. It annoys me and worries me that something is going wrong. Obviously this is normal with a lightweight FW, and not damaging anything, but I would love some feedback to people who may feel the same way I do about noises, but got a lightweight FW anyways. Is the noise really that bad? Also, this is my daily driver (except in the snow). I’m fine with engaging the clutch smoothly, and stop and go traffic with the OEM setup, and I also put the less powerful clutch assister spring on. How bad does the lightweight FW really make daily driving, traffic, hills, ect.? I don’t know if there is a best of both worlds kind of deal, but any recommendations would be awesome.
Clutch- I’m not too worried about the clutch, I’ll probably just end up going with a stage 1, and I’ll more than likely just end up getting a combo kit with whatever flywheel I decide to go with. But again, any recommendations would be great.
Please let me know if you think I’m going about this the wrong way. I love this car… it’s my baby (as I’m sure it is with most G owners), so anything help would be appreciated.

I had to replace all the parts that you need/want to replace. Here's my review:

Southbend Stage 2 Organic clutch: heavier when I first got it, but I dont even notice it now (6 weeks). Grabs nicely, works great, would recommend. PS: I am stock, no mods.
Southbend DXD Flywheel (Steel, 24lbs): I got it due to price and the fact that it can be resurfaced later. It is noisier, I am not a fan of the noise when I am driving with no music. The noise is only really noticeable below 2600 rpm. Above 3000 rpm I don't notice a difference. With music on a moderate level you won't hear anything. The noise is due to vibrations.
After getting everything replaced I read up on resurfacing dual mass flywheels. There are a few shops/companies that do this and do it well. In hindsight, I wish I had pursued this option. I imagine it would go like this: drop tranny, remove clutch, slave, flywheel, ship it asap to shop to resurface, ship it back, put it all back together. I imagine your shop would have to be fine with leaving a car disassembled for some time like this.
I kept my old parts as I was curious, the flywheel didn't look bad at all.

I actually did read through your process though when deciding on the clutch and FW, and you almost hit everything i wanted to know, the biggest thing was the sound though. 2600-3000 rpms isn't that low, especially if I'm doing a lot of traffic driving. I love the idea of revving up faster, but hate the idea of people looking at my car thinking... WTF! Do you have any feedback about the noise and how you feel about it.
Also, i didn't see your review about the CSC. Did you get the heavy duty one?

As far as the clutch. Stage one or two, I'm not to worried about it, clutches aren't really the problem right now. Mainly i just can't decide on the FW and CSC (although I'm pretty sure I'll be getting the heavy duty one).

Go with the heavy duty CSC. There have been no documented failures of the zspeed hd CSC on any of the forums.
The OEM flywheel is a few pounds heavier that the Southbend DXD Flywheel. My readings suggested the lighter the flywheel the noisier it was. I didn't want to be chattering at every traffic light and thus I chose a flywheel that was closest to the stock weight and significantly cheaper.
I'll admit the price was the major motivating factor, I was quoted over a $1000 for a new OEM flywheel. The aftermarket one was half the price.

First off, i think this link is broken.

As far as the chatter goes, mine does not make any noise above ~2200-2400 RPM, and it does not make the noise the whole time before it hits that range either. The OEM FW is almost twice as expensive as the one I bought from Concept Z Performance, and I just got used to "the noise." I believe the benefits (either financial or performance-wise) outweigh the inconvenience.
A lightweight flywheel IS the cause of the chatter. Get the OEM if you don't want any more noise than what we already have from the stock FW.
Also, using a different Transmission fluid than OEM, I've read it insulates this noise a little. I had already replaced mine with Royal Purple by the time I had to change all those parts, so I can't vouch for it.
