So I was reading about clutches and flywheels and came across a lot of talk about cmc in the evo x and how the 9's had an aluminum one. Since I am swapping out the clutch do people usually change out the cylinder as well. Thanks.

bump. Also heard about shifter bushings... would this be a good time to change these as well.
Trying to understand the first part of the question....aren't all evo CMC's aluminum? Is there something special about the IX's CMC?
Generally if you replace the master, you want to replace the slave as well. If both are in good working order, i don't see why you'd change them.
If you plan to swap in new/different shifter bushings, yes this would be a good opportunity.
CMC in the X is held together by crappy glue, that's why people replace them.
CMC on the 8/9's are fine.
thanks. sometimes reading too much info makes you think you might need to change things you dont have to.
...kinda off topic...but...I changed my clutch line to SS after having drama with the OEM one. This is something you can do easily. The part is cheap from RRE and it improves pedal feel and performance + bomb proofs it. I did this after I popped the stocker hose during basic commuting on the 101. Whoever is changing your clutch can to this too. You basically have to take out your battery, battery tray, and stock airbox to get in there. After that it is bolt on/bolt off with one PITA bolt that takes some arm origami to get to. Otherwise, it is really easy. I did my fluids at the same time because of my hose issue.
If you are thinking about changing shifter bushings then yes the time to change them out would be when you are doing the clutch. Is it necessary, no, but if you are going to do them might as well do them while doing the clutch.
More important is the clutch master cylinder. The factory plastic CMC on the Evo X is weaker than the Evo 8-9 CMC which is metal, regardless of how much crazy glue you put on the plastic. Another benefit to retrofittting an Evo 8-9 CMC is that you add the ability to adjust your clutch pedal - something you can't do with a plastic CMC, regardless of much crazy glue you put on the plastic. You might be able to get away with the stock plastic CMC when doing a clutch, but you also might not. Usually, the higher the force required to push the pressure plate, the more likely that the plastic master cylinder will fail.
