Opinions needed:ZSpeed HD CSC or Z1 Motorsports Slave Delete

Juan@Fontana

Zspeed CMAK or even their Internal CSC upgrade is a solid choice. can't go wrong. Have you considered the SpecialtyZ clutch kit that includes an upgraded CSC?

Yes I did look into that option, with many great reviews I’m leaning towards the south bend option, I’m unsure which stage to go with though. I think I will go with the CMAK kit as well to eliminate having to drop the trans again for other than a clutch change. Would purchasing the RJM pedal and RJM HD CMC be overkill to add to the list?

The RJM pedal is great and if you plan on keeping the car for a while, a HD CMC is not a bad idea...

Thanks for the reply sir, I ended up purchasing the OS Giken GT2 clutch, RJM Pedal W/ HD CMC, and ZSpeed CMAK kit. Hoping this setup works well.

Talk to Joe at Z Speed Performance about the CMAK kit and RJM Pedal W/ HD CMC you will be glad you did. There is simply no way around the CSC issue on the Z.

Been a while since I've been on here. So I'm going to assume my CSC is on it's way out.

Background Info: In 04/2021, I was driving to work and happen to notice a different clutch pedal feel. It didn't sink to the bottom, but felt lighter, and after parking at the office, I did notice the clutch fluid reservoir was only half-full, when I've never had to top it off in the 3 years of ownership at the time. No noticeable fluid leaks underneath the car, nor inside the cabin, so I'm thinking it is leaking within the tranny housing. To date, I have not fixed due to many reasons, but to drive it once every 2 weeks to get the oil running and have to top off the clutch fluid once a month.

I am really leaning towards keeping the car for long-term and thus leaning towards replacing the CSC and MC. I have done plenty of research and spent countless hours viewing through the threads of this site. Not sure if some of the veteran members are still around or moved on, but looking to get some insight and opinions.

1. I am hearing and reading more good things about ZSpeed and some bad things about Z1. I've also read that some members originally went with Z1 and will be switching over the ZSpeed. For those that have gone either route, what are your thoughts?

2. I have also read that some members only replace the CSC and leave the OEM clutch. I get the logic/reasoning of replacing the clutch while you have everything out, but is this possible/reliable leaving the OEM clutch? My clutch has plenty of life left and I don't track her at all (2013 Z with only 41K miles).

3. I am most likely doing this myself, but just in case, does anyone know of or have experience with any shops in the Tampa, FL area? There is 1 notorious shop, but have heard HORROR stories about them.

Get the Zspeed CMAK and a new master cylinder. Too many complaints on the Z1 kit. Zspeed was sold to SOHO. So you will be dealing with them.

Hey Rusty! Hope you been well and healthy brother.

I was 99% set on ZSpeed, but your input put me at 100%, and ironically, it's cheaper than Z1's kit. Looks like ZSpeed is currently on backorder through 09.2022, which will give me plenty of time to study and make this hopefully a smooth process.

I wasn't sure if it was Z1 or ZSpeed, but I read that one (or both) are not compatible with OEM/different brand clutches? The OEM clutch has alot of life left and I just can't justify replacing the clutch (i.e. if it ain't broke, don't fix it), and was wondering if it would give me any problems keeping/running the OEM clutch?

Rusty

Other then kidney surgery the first of the year. I'm doing great and enjoying retirement.

I can't tell you about if it will work with an OEM clutch or not. But from reading, the only difference is in the throw out bearing. Joe had different throw bearings for different clutches.
