For Vauxhall Astra 2.0 VXR MK5 Front Grooved Dimpled 321mm Brake Discs KinetixSports High Performance Grooved Dimpled Brake Discs: The main advantages of dimpled and grooved discs are that brake fade is significantly reduced. The science behind this is that the dimples and grooves deglaze the pad and evacuate the gases that accumulate between the disc and the pad during braking. The additional slots dissipate heat more effectively, thus significantly reducing the risk of disc deformation, vibration, or cracking at extreme operating temperatures. Anti-corrosion protection: all Kinetix sports discs come with anti-corrosion protection to prevent the discs from corroding.
