Brake Disc size?

[GoldCJ7]

Hi,
Expecting our new Cali in January, and have seen some 16" steel wheels with winter tyres advertised locally at a good price. Will they fit over the discs on a 150 Ocean DSG non 4motion, it comes with 17" wheels but can't find out anywhere if it has 'big' brakes or not?
Thanks

I have a feeling its only the bigger engines versions (180, 204 etc) that came with upgraded disc brakes that mean 17 inc min wheel size. However i think it was an option to have these on other engine versions.
