A-4 has flywheel or flexplate
automatic trans. has flywheel or flexplate?
SLP sell aluminum fly wheel for LS1 with automatic trans. 2 tenth a second 1/4 mile time faster.
A flywheel is a heavy chunk of typically cast metal that acts as the contact surface of the manual clutch similar to a brake rotor, but also has the teeth around the perimeter for starting the car.
Kind of a crued answer but I think it works.
