They are suppliers of the Rossini Disks / rotors
They give a number to ring for overseas customers. Although you may have a company locally that deals direct with Rossini.
They have got good press reports over here & I can recommend them personally having fitted them previously to my Scenic. Price was not much more than the standard Renaults disks / rotors so I imagine that they should compare favourably with Mercs prices.
