It made a shocking amount of difference. Basically when descending, all I heard was the tires and dirt/rocks. My brain perceived the less audio feedback (bike didn't sound like it was rattling itself to pieces) as the trails being smoother, so I rode smoother/looser/faster. I'm still shocked at how much of a performance difference ~$10 in rubber grommets and moto foam made.
