A lot of parts are made by well known manufacturers but under licence, the clutches are Made by Valeo the largest clutch manufacturer under maserati licence and only allowed to supply Maserati them selves , that way they keep control of charges , its not listed in the valeo catalogue or price list , ive tried many times , took my spare 4200 clutch into a large Valeo stockist and compared it to several similar clutches that were a quarter to a third of the price
The std 4200 Maserati brake pads are/were made by ferodo but ARE listed in their catalogue and price list , got mine form beford batttery motor supplies , front and back £74 inc vat
