I now have 21K on the clutch and flywheel and about 10K on the new Master.Everything is OK and working properly.

Is the Redline fluid still keeping the flywheel quiet? Im just curious, it seems that the redline fluid has a good suppression affect on flywheel chatter/ gear noise from what I have read

HK350 Z

Yes it stays pretty quiet, no more than stock if that....

G.Mello

That's good to hear man. I may be purchasing a South Bend Stage 3 daily and possibly another light weight flywheel. I want to keep noise to a minimum. A few years ago I ran an ACT Streetlite flywheel and the noise was so much it was so embarrassing. The good things about the flywheel was the ease of starting and how much faster it could Rev. So I'm hoping a quieter clutch and thicker fluid this time around will yield a more satisfying driving experience...

The SouthBend package has a silent FW option as well, if you go through Zspeed,I got the regular FW and noise is not an issue.You should be fine.

I just purchased the Stage 2 daily with the csc and master. Did they find out why it was leaking? I asked Joe if that is a common occurrence.

HK350 Z

No they didnt, probably just a bad part in the bunch, it happens.I will be trying to keep the Z for quite awhile, so next time to eliminate issues, I am going with Z1 CSC delete kit.

Nice, thanks for the update. I was thinking about doing the csc delete, but was short on time for choosing parts.

The HD CSC has not gave you any issues, Never needs adjusted and has been a proven fix so how would the CSC delete kit do anything better for you besides adding weight to the car?

and if you read the instructions (i helped install one) it states that it will need adjustments regularly..... about every oil change.....

HK350 Z

True, however I still worry about the CSC, even after 30K miles on it.I saw this newer product and thought about going that route on the next clutch I install.

Just a thought though, if the CSC holds up until my next clutch, then no worries I will be coming back to you for another clutch kit/CSC and MC.

HK350 Z

Yea, I read that on thier description of the product.

HK350 Z

Been almost a year since last update, at 149K currently, kit has held up well since replacing master.

I will be keeping the Z for another 4-5 years, Joe I will be ordering another kit from you with no hesitation next year around this time.She still pulls hard and engages well.

Cant wait, 6 months she is paid off and then time to start the rebuild...

Sweet now this is an update thread. Definitely know the direction ill go with clutch!

HK350 Z

OK Update to clutch kit. I am at 169k and my fluid level is at minimum.I have had the kit for about 64k miles and June will make four years.No slipping but pedal is starting to stick.I am not doing the upcoming clutch job,my shop is and they can tell me where I am losing fluid at.Dont have any fluid inside car below clutch pedal so I don't believe it's the master.

I just ordered new Zspeed Stage 1 Quiet clutch kit with new hydraulics from Joe again. I was more than happy with the life I got out of the kit,day one I said to myself if I make it to 75k-100k with no major issues I would go with Joe again.I also have a Bilstein kit,Diff,FCA,Rack/Pinion ,and Subframe bushings (all from Zspeed) ready to go in as well.Thankfully I can resurface my South Bend flywheel.

Only reason I did not go with the CMAK delete is it is new to me.I have no doubt it's a great alternative,I would just rather roll with what I know for now which is the HD CSC.

I will and have bought plenty of parts from Joe over the last year(s) ,and will continue to do so.He answers all my silly questions and ships quickly and correct parts.I will update again in a few weeks when car goes in shop and they tell me where fluid loss was from.

Thanks Joe, for all your help and quality parts for the Z.I am in full rebuild mode and you will definitely be seeing more orders in the future.

Thanks, HK350, for sharing and keeping track on all this. This kind of stuff is the most useful and wanted on specialized forums.
I'm in process of choosing what clutch kit to buy and how long it'll last.

What was the reason of choosing "Zspeed Stage 1 Quiet clutch kit"? Will it make the same 60-70k with no issues? Does it make sense to try South Bend kit first or there'll be almost no difference for the bone stock HR Z (and almost no track or drag racing)?

HK350 Z

I chose it as I don't have any mods and don't plan on any going forward. Clutch longevity depends on a lot of factors.
