How come? I will not be using my car for loads of track use and i will have 18" wheels so as they are the same piston size would the bigger disk diameter be better?

For road u don`t need bigger disks as stopping power is equal, but weight difference (Ap5570 10.4kg and AP7040 13.9kg kit) and also AP5570 fits under 17 inch wheels. So bigger is mostly for the looks.
Are the rotors AP Racing? What is the product number?
Kit is Genuine AP7040 355mmx32mm
Calipers 6pot with dust seals
Disks and bels AP for 100 and 114PCD hubs with AP alloy brackets
Brake lines Goodrich steel
Pads Ferrodo 2500 1 set nearly new, second 70% left
So basically direct fit to any impreza. Even fit under Team Dynamics 1.2 17inch wheels.

P.S. rear brake kit added
I see this statement used a lot and I totally disagree. Basic physics dictate that the stopping power is NOT equal. The force is applied further away from the axis on the bigger disc (think longer spanner - leverage effect).
However, I agree with the point that probably unnecessary for the majority of road users and limits wheel choice. The other downside being an increase in the unsprung weight.
