The flywheel’s job is to transmit inertia to get your vehicle moving in the right direction. Though it may seem smart to use the heaviest possible flywheel to make it easier to transmit more inertia, the truth is, selecting the right flywheel for your ride is way more involved than that.

…Which is why we liked this video from Ram Clutches.

It’ll walk you through the question of whether you should use a heavier steel or lighter aluminum flywheel on your street car, and give you some other key factors to consider—including things like gearing, drivability, and cam/idle quality.

The video is just under two minutes long and loaded with some vital flywheel tech, so give it a watch if you’re weighing (pun!) your flywheel options.
