Specialty Z Max Street Flywheel, Clutch, CSC

Any update on this? Were you able to fix the problem?

I shortened the piston then re-bleed the system again a day or two after that post. It's back to being drivable again. However, I'm still bothered by the amount to travel before engagement which is about 1/2 way depressed. I feel that the car is no longer a good daily driver anymore. She drives fine and is still a hoot to drive but I have to "work" when I shift now. I might have to get the RJM pedal to remedy this problem. That in itself is bs in my book. Sure the pedal is super cool and functional but the fact that the "new clutch" does not "feel right" sucks. I'm thinking of asking a local member with the same/similar setup if I can stomp on his/her clutch (no sexual intent here) and see how it feels.

Ps, the clutch, flywheel and csc looks and feel very very well made. It's the functionality that sucks so far.

I'd like to apologize in advance for any novice thinking right here if it is the case.


love the review - i've been very interested in replacing my clutch for a much grabbier one, as i prefer really really low engaging fast grabbing/lurch your car forward once you start releasing the clutch-kind of clutch. My bmw m3 engagement is literally half an inch off to an inch off the floor, with a small window.

I've had the RJM pedal installed on my stock clutch for a year now. It's definitely night and day from the stock pedal. I've set it as low as i can (i think). I did notice that you give up a little clutch stiffness when lowering the friction point. I also noticed that you give up clutch grabbiness by widening the clutch engagement point.


With the ZSpeed clutch do you think it's possible to keep the clutch engagement point really low, with a relatively small engagement point for grabiness?

axmea?

Any long term reviews from those who have had this for a long time? 20-30k + miles.

My clutch pedal engagement is back to being 2'' off the floor again. Driving the car is a pain now. There is no way to slip the clutch or drive her "smoothly" now. There is just not enough pedal play. The extra grabby clutch adds to the difficulty of shifting. To give you an idea on how bad it is. My head jerks when shifting from 4th to 5th gear.

I'm going to E-mail Specialty Z and see what they think. I mean I have bleed her like 3 or 4 times with 3 people, one at the reservoir, one on the pedal, and me under the car at the bleed line.

I really hope I don't have to remove the transmission again. But, if do, I will. I will check back with updates.

Thanks for the continued feedback.

I don't need a clutch quite yet (actually probably not til 2016, since I am out of the country for a while). I was leaning towards the SpecialtyZ kit. I'd planned on the RJM pedal anyway, so I am not necessarily concerned about the clutch engagement in terms of enjoyability. however, it does concern me that it seems to be designed this way. Which makes me wonder, will it cause undue problems by putting stress on the transmission or at the very least the hydraulics.

It'll be interesting to hear what SZ has to say.

In all honesty, the kit looks very well made. Then again, I don't know jack about these type of things. The car drive fine other than that it is one hell of a jerky ride since it's an on/off with no in between. Knowing what I know now and had to pay again, I would not necessarily pass the Specialty Z kit up yet. I will see how things turn out with the CS side and how they can help me handle the issue.

Any update on this? I'm literally about to order my 6puck setup tomorrow, replacing the master slave at the same time and swapping to Redline tranny/rear diff fluids.

I've been through two of the max Street clutch kits in 3 years. I had them install it after having the typical slave and master cylinder issues and needed something reliable for tracking. The first one lasted a year, possibly the installer setting it up incorrectly, but I've been told that the clutch disc/plate manufacturer is known for poor stack construction.. the components showed signs of tearing and burning when it was disassembled. The second one just started slipping at 23000. One light track day and daily use on each with 320 wheel hp manual 6. The first one was fraught with pressure feel and chatter issues. The second one Sebastian rebuilt and put it in himself and it functioned quite a bit better until yesterday. Not going with this setup again.
