Honda Civic - 2017-2021 : 1.5L Turbo (EX & SI) | FW-150-TDA
When upgrading the 1.5L Turbo engine in the 10th Gen Honda Civics, the stock
clutch and flywheel leaves a lot to be desired. Quite quickly the stock clutch
becomes incapable of supporting power upgrades and more aggressive driving on
a race track. Clutch Masters offers a complete lineup of single and twin disc,
as well as single mass aluminum and steel flywheels to suit your cars current
and future needs.
This listing is for the twin disc flywheel only
The Clutch Masters FX725 is a 7.25" (184mm) Twin Disc clutch and is the
ultimate in twin disk performance for engines/transmissions with smaller bell-
housings that are focused on drag racing. Clutch Masters FX725 Twin Disc
systems are developed from decades of experience in drag racing. Because of
the minimal rotational mass the FX725 isn't ideal for the street but with
improvements in friction material over the years we have been able to create a
solution that can handle occasional street driving. The FX725 is designed to
hold tremendous horsepower and torque, while maintaining reasonable peddle
pressure to operate on the track.
The cover assembly is machined from billet aluminum and is then Type 3 hard
anodized. Our billet covers have roughly 25% more tensile strength than the
competition’s cast unit. By focusing our ability on machining the strongest
cover possible while maintaining minimal weight, we are basically able to
eliminate any flex in the cover. Our billet covers see only .003" of flex
where as a cast or stamped unit can see as much as .030" of flex. By
eliminating this flex in the cover, the driver is able to operate the clutch
much more consistently and confidently. All the movement being applied to the
diaphragm of the clutch from the throwout bearing is used solely to engage and
disengage the clutch and isn't wasted by the cover flexing first. The strength
of our covers also results in greater clamping force over the same amount of
area vs. a cast or stamped cover. This means our twin discs are easy to drive
and have superior clamping force to make sure all the power your engine is
making is being utilized.
What makes our FX725 and FX850 Multi-Disc Kits truly special, and a feature
unique to Clutch Masters is our QR System, or Quick Release Pressure Plate.
The QR System Incorporates three spring-loaded bolts allowing the pressure
plate to engage and disengage evenly and smoothly while reducing internal
clutch noise/chatter by up to 50%. The QR System was developed to provide
quiet and smooth operation for the street user while delivering the
performance a multi-disc race clutch needs.
Flywheels are made for each specific application in either aluminum or steel.
Our aluminum flywheels are machined from billet 6061-T6 aluminum to meet SFI
spec 1.2 for competition in NHRA, NDRA, IDRC, IHRA, SCCA and NASA. Aluminum
flywheels are Type 3 hard coat anodized to ensure their durability and
performance lasts. Each aluminum flywheel includes a replaceable insert. Steel
flywheels are machined from 1045 billet cores and are then black oxide treated
for rust prevention.
