OK, didn't realise they were that light.
Surprised by that.

Are the lightweight flywheels worth investing in for a track only car?

When I got my Billet Flywheel I was amazed how light it was I thought this is going to make so much difference until I took the standard one out and realized how light and OEM one is lol
