En collaboration avec des universit\u00e9s et des laboratoires m\u00e9tallurgiques, Sinter a d\u00e9velopp\u00e9 une nouvelle fonte grise contenant du carbone (GJL 250), qui offre un coefficient de frottement jusqu'\u00e0 20% sup\u00e9rieur \u00e0 celui de la fonte grise conventionnelle.
Un disque sp\u00e9cial en fonte grise avec une fine couche de c\u00e9ramique a \u00e9t\u00e9 d\u00e9velopp\u00e9. Ces disques de frein offrent non seulement un coefficient de modulation et de frottement \u00e9lev\u00e9, mais ils n'ont \u00e9galement pratiquement aucune usure, comme les disques MMC.
Ils ne peuvent \u00eatre utilis\u00e9s qu'avec les plaquettes de frein 2032 vertes sp\u00e9ciales.

Le nouveau mat\u00e9riau composite pour disques de frein appel\u00e9 MMC (Metal Matrix Composite) est trois fois plus l\u00e9ger que la fonte. Cela signifie que le kart acc\u00e9l\u00e8re plus vite, freine plus vite et tourne plus vite dans la courbe (moins de poids, moins de balancement des disques de frein). Les disques de frein MMC ne peuvent \u00e9galement \u00eatre utilis\u00e9s qu'avec les plaquettes de frein 2032 vertes sp\u00e9ciales.<\/p>\n
