It is worth remembering that a lightweight rigid flywheel provides uncompromised throttle response at the expense of eliminating factory damping elements. This results in a more direct drivetrain operation, which may lead to a natural increase in audible gear mechanism noise. This is a desirable characteristic in sports vehicles resulting from the rigid connection between engine and drive.
