I'm really curious about these truely having less drag, and if they do whether it's noticeable in any meaningful way.
They only start working when you're cornering and presumably also braking or slowing down, so having less drag in the drive line at that moment seems negligible.

Perhaps in long fast corners you'd have small gains?
