370z Clutch fork/pivot ball. Quesion

south · 04-18-2021, 07:51 AM

I do know that these cars have a hydraulic system, im currently trying to diagnost a hard/stiff clutch pedal. I was wondering if our cars have a clutch fork and pivot ball. I’ve seen that 350z’s have these problems i was wondering if it was possible to happen to a 370z. If so does anyone have any pictures?

They do not have a clutch fork in stock form. It was replaced with the garbage csc.

If it's all stock it's the pedal assembly. Some people mess with the spring others like myself tossed the whole assembly and use the RJM pedal.

I have a action stage 3 clutch, with the hd slave i just replaced thinking it was that, also have a zspeed clutch hose and a new oem master from zspeed aswell. How would i check the pedal?

Ffs. "I can't figure out why my stage 3 clutch is stiff"

Are you for real?

Anyway. The rjm pedal will help help lighten the pedal pressure from super stiff to lighter than stock depending on how you set it up. That is the only thing than is going to help a very heavy clutch not feel as heavy

I cannot speak for the HD slave cylinder with that setup, but I have a similar setup:

Action Stage 3-1ms (6 puck)
Zspeed CMAK
Standard pedal
modified helper spring.

The I would rate the overall feel as "moderately stiff" on my setup, but it's not exhausting. I have driven a boosted Z with the Action Stage 5 (HD CSC) and it was wayyyyy stiffer (edit: I saw on the manufacturer site that the stage 5 is expected to have a heavier feel). It could be how the the CSC works with the pressure plate. Since the CMAK has a traditional style clutch fork, there is some leverage to create the pressure, so I imagine that is why my clutch is relatively easy to use. My OEM WRX clutch honestly feels almost as stiff as the Z, but that could also be due to the seating position.

Hopefully that's helpful.
