The grooves help deglaze the pad and prevent fade which occurs when the pad and disc gets too hot! The holes help to keep the discs cool and dissipate heat! The grooves also help to channel water away from the disc surface! Stopping distances are reduced! They add the finishing touch behind alloys! No modifications needed to fit!
