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.
