I have standard discs and pads on the rear, as long as they are in good condition it really dont matter.
On the front i have put some good discs and pads, brembo max discs and green stuff pads, they work well together.
The pads are known for not lasting long, but i have had mine on about 15k and they are ok (lot of motorway miles)
I would suggest just putting a good set on the front, and rears standard. Rears dont do a lot of the breaking unless you have a lot of weight in the rear.
