RJM Clutch Master Cylinder Kit?

I'm aware of the CMC issues with our cars, that's why I was asking about the kits. I'm under the impression that both kits are to fix the same issue, am I wrong?

Some have never had an issue with the CMC. But ive personally been threw 3! 2 factory and 1 luk brand same outcome. Ill no if its money well spent in a year. I upgraded my csc and now i upgraded the pedal and cmc too, see how it holds up.

Both the RJM Performance and Z Speed Performance clutch master cylinder kits are both to fix the possible issues with the Nissan OEM clutch master cylinder. My Nissan OEM clutch master cylinder failed just after a track day as I said clutch master cylinder failure can happen. That is why it is best to install a heavy duty clutch master cylinder and correct it before it can become a issue. The bonus is you can completely flush all your fluid with better fluid.

But you said you got the RJM AND the ZSpeed one, so I got a little confused there

RJM makes a heavy duty clutch master cylinder (HD CMC) as well as a clutch pedal assembly. Z Speed makes a heavy duty concentric slave cylinder (HD CSC) as well as a clutch movement alteration kit (CMAK) that moves the slave cylinder outside the transmission bell housing. Z Speed also makes a HD CMC, but it's only for the 350Z and not for the 370Z. It's generally recommended that the CMC be changed any time the CSC is changed. Trust this clears up the confusion.

Ah, I see, so people buy everything? HD CMC kit, HD CSC kit, and CMAK kit. I think I will just buy the pedal then, and buy that stuff later, when finances allow it.

CMC = clutch MASTER cylinder. CSC = clutch SLAVE cylinder. Two different parts.

Aftermarket slave cylinders from ZSpeed are the HD CSC (internal option) or the CMAK (external option). Don't buy both.

That would be the Z1 CSCEK that has issues. I have one. Will be going to the ZSpeed CMAK (external) when I replace the clutch. The CMAK is self-adjusting.
