New brakes for Clio MkI (williams)

[Bad-i]

Hello Everybody, I have tried to find some information but I could not get a clear answer.
I do have Clio "maxi" based on clio williams and I am thinking about putting some bigger brakes to it.

I am thinking about 285 mm brakes (because I still want to use 15" wheels for training). Could you be so kind and help me with some ideas what brakes would be best in such size?
