Ok guys, sorry to burst your bubbles.
I've been plaque by the master clutch cylinder problem the last few months.
My 2nd unit burst within 10 days after the 1st one broke. After the 3rd unit was installed, I baby the car until the AMS ring came & got it installed immediately. It was finally good until today that is (approx 1 month).
All of a sudden, my clutch pedal would not return after I depress to engage gear (exactly the same as when the master clutch broke) except that the cylinder did not break or leak. The brake fluid level is level is stable.
I had to tow my car to the workshop again (3rd time within the last few months for the same problem). Since this is Sunday, the mechanic are not working but initial diagnosis indicate an "internal leak".
I am really pissed. Sure the AMS ring prevented the cylinder from breaking but it is not the SOLUTION.
I am going to get my workshop modify a 9 cylinder to fit.
Those designer at Mitsu ought to be

My workshop has replaced the clutch cylinder with a E9 model. I did not get to see exactly what was done but I know for sure they route a braided hose for the brake fluid.
According to them, they have already perform this mod for a few X already. No problem so far.
The pedal feels higher, more positive.
I also notice the gears are easier to engage as well.

So how much time and what is involved in installing the AMS reinforcement ring?
I'm thinking that I better get this installed BEFORE it fails or I will out of commission on my daily driver.

I haven't done it. I did look at the instructions, and I would assume 4-6 hours moving slowly. The whole clutch pedal assembly has to be removed, might as well do the SS clutch line as well.
My workshop took about an hour to install the AMS ring including bleeding the brake fluid.
I don't know of anyone else having the same problem as I do but at least the ring prevent the master cylinder from breaking in 2.
It is no joke when the cylinder break, a loud bang & your clutch pedals on the floor. Imagine having to wait for the tow truck to tow the vehicle esp if you're located in the outskirt or interstate.
I strongly suggest anyone with the manual X to install the AMS ring or try the other solution cos it is going to happen sooner or later.

woa...
ok
go to the catalog of tilton i believe 'pre' ams cilinder ring...
when carrito's clutch had the same problem they replaced it w/ a tilton master cilinder, i believe it was the 76-Series Master Cylinder (but dont quote me on this)
you will need the cilinder a heim joint and obviously the time and tools to do it...
heres how it was done
theres your permanent solution

AMS has the stainless line out too. I will be doing both in a few weeks. AMS estimates it as a 3-4 hour job, maybe more if you are taking it slow or your first time doing it.
I just have heard of too many failures even with the reinforcement ring so I think I want to swap out the master cylinder itself. If I'm going to all the trouble of taking that all out I may as well swap it for something else. Anyone that has done a swap to an EVO 9 one please let us know what is required (apart from the line).

The first one, a larger pump was used and made the pedal a little stiffer than expected (althoug it still works flawlessly), but if an smaller diameter pump is used the pedal feel would be even better.
Plus:
- The pedal height is adjustable
- The pump is 100% rebuildable (if it ever fails, ha ha ha)
- Muchhhhh stronger than any other option
