We have two member in our NY club who've experienced
slipping with this clutch. One member ultimately having to
prematurely replace the clutch.I personally installed the full face MAX clutch on a freshly
machined stock flywheel with step for the member who had to
recently replace it. Followed SZ's clutch adjustment to a T as
well. The Z is the typical stage III and the person drove very
normal with no racing at all. The engagement felt great and
solid, and no slipping was apparent for the first few months.
We have had some typical cold temperatures here during the
winter and this is when the slipping is most noticeable. The second member with this clutch uses a RPS segmented
flywheel and is running 15psi with supporting mods on GT28R
turbos. He also has pedal adjusted to SZ's instructions. Last
night his clutch was slipping worse with the temperature at
35degrees. I personally am a RPS customer myself however I am running
the same NA Sport street clutch which I used on my previous
NA, now on my Stage 3 setup as shown in my profile. I have
noticed the power that this clutch usually holds at 15-17psi on
a warm day, does not hold true for a cold night such as last
night at 35deg in 4th and 5th gear...however I remain
completely satisfied as my clutch is not rated to hold such
power to begin with. It looks to me the MAX street disc uses the same friction
material as my Sport street disc however with a higher
clamping pressure plate...someone should clear this up for me. So...I can't seem to think of this as a coincidence that both
people had slipping issues revealed in the cold temperatures,
and this leads me to question whether the material used,
which looks like the typical organic mix actually holds true to
its rated Torque rating in colder temperatures. What else can cause such issues? I certainly can't think of
anything else other than the clutch being at fault...
