Street
/ Strip Discs
Organic,
spring center replacement disc designed for smooth engagement, quiet
operation and improved durability. We offer the best brands for the
application. Street ACT Clutch discs can be used with moderate to
heavy duty applications including racing depending on torque output
and heat. View our application chart for more information on torque
capacity. When a special act Performance Organic disc is available
the suffix "S" will appear in the disc part number. These discs use
special performance linings that are designed to withstand high heat
and high RPM. When the suffix "M" appears, the disc has been modified
by reducing the marcel enabling quicker action. If you have questions
about a certain application consult us. With all the hype about different
lining materials available we still contend that nothing can beat
a good quality organic disc for street use. A good example of this
is the Eclipse/Talon AWD Turbo. This application can be especially
hard on clutches because of all wheel drive, the heavy weight of the
car, and limited clutch size. Yet because of the durability of the
Performance Organic Street Disc, many of the fastest Eclipse/Talons
owners enjoy smooth engagement, 11 second and even 10 second timeslips.
This same act performance lining is available for several applications
where there is a particular need. It takes a lot of abuse and yet
engages smoothly.

Copper
Ceramic Race Discs Xtreme Discs
Available
in 4 or 6 pad design. These pads (pucks, buttons) are highly durable
and resistant to heat. They actually perform better when hot! The act
copper ceramic material holds approximately 28% more torque than an
organic lining. Copper ceramic discs engage fairly harsh and are not
normally recommended for street use. The ACT Clutch high copper content
of the material helps to absorb heat and reduce the temperature of the
mating parts. Shifting is quick and sure due to the lightweight rigid
design. No worries about broken center sections or springs. 6 pad discs
are recommended for larger sizes to absorb more heat and for smoother
engagement than the 4 pad disc. ACT Clutch 4 pad discs engage harsher
and shift faster. They are well suited for smaller disc sizes from smaller
engines. We can provide any size 4 pad disc up to 240mm or 6 pad disc
up to 250mm with the spline sizes listed below. Our application chart
lists only those racing discs used with our pressure plates although
we fit many other cars not listed on our chart. If you have any questions
regarding ACT Clutch applications not listed,

Heavy
Duty Pressure Plates
Great holding
power, better 60ft & 1/4 mile times, and long life are all benefits
that come along with these plates. What makes our ACT Clutch pressure
plates the highest standard of the industry? First, we start off with
new ACT Clutch units. We do not offer rebuilds (except for special
circumstances or warrantee work). Second, we increase the pressure
the right way: by changing the diaphragm. Our ACT Clutch diaphragms
are specially heat treated through an exclusive 3 stage process and
then hardened on the release bearing contact area to reduce wear.
Third, we make sure that the pressure curve and release travel of
the unit is in the right working range. Forth, we use proven assembly
procedures that insures consistency and precision. Finally, we accurately
balance and test every unit we produce. No guesswork, no hype, only
proven engineering and calculated results.

Xtreme Pressure Plates
The maximum holding power available! Our solution: apply more diaphragm
pressure. With a less aggressive ACT Clutch street disc, this makes
a great combination for high HP street cars that prefer smooth engagement.
For racing, combine our act Xtreme Pressure Plate with our ACT Clutch
Xtreme Disc for the ultimate in torque capacity and durability. What
makes these units so unique is a radical increase in pressure without
altering the proper geometry or stacking of diaphragms. The result
is maximum holding pressure and long life, while maintaining good
release clearance for fast, clean shifting. This can only be done
with a specially engineered diaphragm. On some units, like the one
shown above, we actually include gusseting the cover to reduce flex
caused by the the high pressure. These are made with the same high
standard as our heavy duty pressure plates. You will find these on
many of the fastest cars on the track. How do they feel? A little
stiff, but smooth! ACT Clutch Xtreme Pressure Plates can be identified
throughout the application chart when the pressure plate number is
followed by a suffix "X".
