It would be interesting to know the size of the wheels that this test car was running. They look like 18s but probably are 17s. The reason I ask is that those brakes look very tightly assembled in those wheels and I would bet that you couldnt get a smaller wheel in there. Which also means that when the 135i does come, you will probably get 17s as standard (as opposed to the 328's rather poor standard 16s)
