There other other advantages which I won't go into here in case the FF regs don't allow them.

FF 1600 regs mandate standard Ford flywheel. You can machine to minimum weight of 11.79kg for flywheel and pressure plate so you can take a few kgs off. They are still pretty hefty though which might explain why they don't shatter. Also, these cars weigh 400kg so maybe the stress on components isn't as great as with a Cortina.
