Are you sure this is an M-sport package... could very well be the "Performance" bodykit, looks a lot like the ones available for the 3 and 1 series.
And about the wheels? I'm prety sure that these are the type 276 wheels that are already available in the accessory catalogue, they come in 16 inch as well as in 19 inch...
Could be wrong though.
