stock flywheel was designed with extra weight to make
daily stop and go driving as easy as possible. The disadvantage
of this weight is that your engine has to use more power
to accelerate the flywheel which causes slower revs and
an elastic feeling when engaging the clutch. If you're
building your car for higher performance, a Bönez
Lightweight flywheel will allow the engine to accelerate
quicker with more power getting transferred to the asphalt.
For comparison purposes, the stock flywheel weighs over
20lbs, but our Chromoly flyweel weighs only 10.65lbs.
most popular flywheel for the non-turbo FCs. Lightening
up the flywheel does so many things for the car. Better
engine response, smoother power, easier shifting, more
power to the ground to mention a few. The lightweight
steel still has enough mass for easy everyday stop
and go driving but still snappy for those weekend track events.
This flywheel weighs 10.65lb and really transforms the car.
These flywheels will work with either the 12A or 13B engine,
as long as the correct counterweight is used. They can also be used
with the 79-82 engines (with the correct counterweight) in order to
upgrade to the updated 225mm clutch configuration.
Includes necessary installation hardware but requires counterweight
(sold separately, see below).
225mm Light Steel Flywheel - 83-85 Rx7
A rear counterweight is required when upgrading to a performance flywheel.
There are tdifferent counterweights to match the different year models and types of engines in the Rx7 (12A or 13B).
The counterweight needs to be matched to the correct
year of engine, not the year of car that the engine is getting installed
into (They can be different when doing an engine swap), they are not a "one size fits all solution".
These counterweights work with all the flywheel that we offer and most other popular flywheels.
