Brembo developed replacement that meets or exceeds OEM specifications. Includes a fixing screw kit with all the necessary hardware for simple, more efficient and safer installation. Aluminum Hub - Considerable weight reduction of the disc, with benefits in terms of performance and emission reduction. Braking Surface-Hub Connection - Allows braking surface of the floating discs to expand without causing permanent deformation. Grooves/Drilling - The use of grooves and holes on the braking surface creates the following advantages: Continuous revitalization of the friction material, Improved cooling, performance in wet conditions and resistance to fading. Enhanced Performance Venting - The use of Brembo Pillar Venting Technology or directional venting allows improved cooling and greater resistance to cracking.
