Wilwood Heavy-Duty Clutch Master Cylinder

djrelic · 01-16-2013, 06:18 PM

I found this the other day on zspeed.com

Zspeed Performance Wilwood master cylinder upgrade

This looks just like our OEM one. Does anyone have this or can chime in?

Just wondering...

I bought one of those 2 weeks ago , I havent had time yet to install it .
Im waiting on the RJM pedal assembly to go any further since im swaping in the 6MT instead of the 7AT

The hell... how hard was that switching your 370z from auto to 6mt?

What? An aftermarket master for our cars now? Joe had one available for the 350 for awhile.

You guys might want to check again. For VHR an abs module gets in the way, unless there is a solution to get around it.

I wasnt aware of the possible problem with the ABS module since I havent heard of anyone going with an aftermarket master cylinder.

anyway Im ditching the ABS out, so that wont be a big issue !

well since I still had a spare HR engine/tranny + ECU from my 350z old days.
the switch from 7AT to a 6MT isnt too bad
I could have went on the cheap side with used OEM stuff (clutch pedal assy. master cylinder and hose...) but I didnt.

we just did one on an 08 hr car with a giken twin disc, the pedal pressure was defnitely a lot better.

Good to hear. I'm hoping for something that fits the VHR platform so I can get one once the OEM one fails again. It gets mushy after a few months, and doesn't feel quite linear.

It will not fit the 370Z, Only fits the 350Z. The ABS module is the problem and gets in the way.

We are working on a full custom master for the 370Z/G37. It will be a complete custom made piece.

G.I. JOE!

just wondering, why didnt you just buy a 6mt in the first place?

Why?

im not gonna debate a 7AT Vs 6MT
but I will share my experience with you since you asked

When I had 6MT 350z in the pass and was tracking it as well. It was good and everything then when the time came for the 370z. The 7AT proved to be a much more advance auto tranny than their previous one on the 350z which suck.

7AT with its paddle shifter was quite attractive and very fast shifting.
I was 50/50 between the 2 of them. Im not into drifting so the use o the clutch isn't that needed.

So after going on the track and being quite aggressive I discovered some flaws on the 7AT that made me switch back to the 6MT mosty because I blew the VVEL head and I didn't want to put another VVEL engine in there and I went with the HR head swap

Budget was another big reason since the warranty didn't cover my engine.

The 7AT needs the 370z ECU to function and since it wasn't there anymore I couldn't use it and then find some fix to correct the flaws Ive seen on the track.

Nothing yet, We have not had time to work on it.....

I'm curious if anyone knows the long term effect of changing to an A/M clutch CSC and leaving the stock MC in place, is there a one to one relationship between the MC and the CSC? In other words, can the A/M CSC cause the MC to work harder etc pushing a different load -for lack of a better word- than the stock CSC?
I haven't seen any complaints but I have read that a lot of guys have a CSC that fails, they replace with an A/M CSC, then later have to replace the MC. Is it just a coincidence?

Joe@ZSpeed · 07-12-2013, 10:56 AM

We always recommend a new master cylinder with a new slave, Its like replacing your oil and not the filter.

Master CYL is just as worn as the slave, The same amount of crap/dirt and grime is in the master as is in the slave cylinder.

It's a matter of once you open the system, if the master is weak, it will not work correctly.

Our slave puts no more load on the master (actually a tiny bit less load/pressure) than the stock slave does, The clutch itself is what's going to increase the load on both parts.

The master cylinder is a $100 part, Why would anyone spend $1500+ on a clutch, Slave, Flywheel and not replace the cheapest part in the system?
