TranstarFlexplate

The flywheel provides mass for rotational inertia to keep your car's engine running. Otherwise, the engine will stall when you let your foot off the accelerator. It balances the engine. A flywheel is specifically weighted to the car's crankshaft to smooth out the rough feeling caused by even a slight imbalance.
