Bigger Flywheel

[BKH808]

For my 20v swap I have a spare 212mm flywheel which I was planning on using but what are the benefits of a 212mm from a 20mm flywheel?

black top flywheel is lighter than all other stock 4ag flywheels. slightly more friction surface(consider it like upgrading to slightly bigger brakes) not a noticeable difference, but, doesn't hurt.
