Most stock
flywheels are heavy cast iron parts designed for optimum
street driveability by soaking up some of the power from
the engine and putting it in
storage in the form of inertia. Although this may be
important for transporting
the groceries, this driveability comes at the expense of
engine response and acceleration. Light weight flywheels
keep less inertia in storage but the lighter rotating mass
provides significantly improved engine response and
acceleration characteristics. Until now most aftermarket
flywheels for sport compact vehicles presented certain
undesirable concessions to the user. Many are too light or
fragile for the application, others have reliability
issues and all are very expensive.
Finally, ACT offers eXACTly what performance enthusiasts
need: all the benefits
of a premium quality light weight flywheel at an
affordable price.
ACT currently manufactures XACT flywheels in two versions,
ProLite for road
racing
applications and very quick throttle response, and
slightly heavier StreetLite for street and drag racing
vehicles which may require more inertia. For example, the
Integra ProLite weighs 8.8lbs and the Integra StreetLite
weighs 12.5lbs. Both
ProLite and StreetLite flywheels are precision made from
Chrome-moly forgings
and feature an induction hardened integral ring gear. All
ProLite and StreetLite flywheels are CNC machined, heat
treated for strength and precision balanced. Substantial
material is left behind the clutch surface area for better
heat
dissipation and durability while weight savings is made
where it matters the most
for reduced inertia.
XACT flywheels are certified by ACT to meet SFI Spec. 1.1.
This makes XACT
Flywheels legal for competition when SFI Spec. 1.1 is
required or recommended.
XACT flywheels come complete with official SFI sticker and
serial number as
required for certification. Consult the following chart
for available applications. Some may still be in
development at the time of this printing. Numerous
applications
not listed are scheduled for release next year.
