The ScienceofSpeed Billet Twin Carbon
Clutch & Flywheel is a revolutionary clutch for the S2000 for customers
with high horsepower engines.
Typical high horsepower clutches for the S2000 can be difficult to drive. This is because in
order to hold increased power, manufactures have had to greatly increase
the coefficient of friction (making the clutch very difficult to engage)
and produce a very high clamp load (making the clutch pedal very stiff).
By making the car difficult to operate, these clutches affect an
important interface of the driver to the car - ultimately taking away
from the joy of driving the S2000.
By using true carbon-carbon discs in a multi-disc design, ScienceofSpeed
has been able to take advantage of the unique properties of
carbon-carbon discs to design a clutch that is easy to engage with a
pedal effort that is close to stock. |

The ScienceofSpeed Billet Twin Carbon
clutch is the only true carbon-carbon clutch designed for the S2000.
Other clutches, even multi-plate clutches, are still difficult to drive
because the high friction discs used. |

|
|
carbon-carbon friction liners: |
|
The clutch is made up of two discs, a
pressure plate, mid plate, and flywheel. This design uses eight carbon-carbon lined surfaces to increase
the smooth engagement of the clutch. The carbon-carbon friction liners
are developed under pressure and heat for six months to develop a near
pure carbon-carbon structure. The carbon-carbon discs allows the clutch
to hold high load while offering smooth engagement and long life. |

|
lightweight twin disc design: |
|
The twin disc design results in a very
high surface area in a compact design with the mass centered in the
clutch for fast engine response. This compact design results in a low
moment of inertia - and an overall lighter weight - 24.5 lbs. The clutch
pressure plate is designed to captivate the floating mid plate. Like
other floating mid plate clutches, a faint noise is heard when the
clutch pedal is depressed. Unlike others however, this design uses the
aluminum pressure plate rather than the steel flywheel to captivate the
floater. The result is a decrease in noise and a much lighter assembly. |

light pedal effort & easier
engagement: |
|
Thanks to the properties of the
carbon-carbon liners, a much lower clamp load is required of the
pressure plate to hold the power. This results in a very stock-like
pedal pressure making the clutch easy to drive on both the street in
stop and go traffic or at the track. It also results in less wear and
tear to the engine's thrust washer bearings. Due to the carbon-carbon on
carbon-carbon design, the engagement is much smoother than typical
carbon or ceramic style clutches. While the engagement is sharper than a
factory clutch, the relative smoothness allows manageable drivability,
even on a street car. |

|
high power capacity: |
|
The ScienceofSpeed Billet Twin Carbon Clutch is rated
to 700 lb/ft of torque at the wheels - torque which would be typical of
a 1000+ hp S2000. The clutch is of course
equally of handling anything between this and completely stock power. |
|
|
|
high technology & build quality: |
|
Each ScienceofSpeed Billet Twin Carbon Clutch is
pinned and balanced after assembly for a precision fit . In addition, the high strength
pressure plate design eliminates tension straps for best reliability. |
|
|
|
factory fitment: |
|
The ScienceofSpeed Billet Twin Carbon
clutch is designed to work with the factory slave cylinder and
transmission and requires no modifications for installation. Both
release and pilot clutch bearings are included with the clutch. |

installation notes: |
|
For performance and durability reasons
required by the high horsepower application that this clutch is designed
for, please note that the ScienceofSpeed Billet Twin Carbon Clutch is a
strapless and free-floating plate design. Due this this, a slight amount
of noise is normal to be heard only when the clutch pedal is depressed
and held. In addition, a slight amount of shudder will be felt when
engaging first gear from a stop compared to the factory clutch. Keep in mind however, compared to other
high horsepower clutch options, both the noise and shudder has been
substantially decreased by a special design of the pressure plate and
discs. This clutch is undeniably the most easy driving clutch that is
rated for this level of power. |
