I've got a S-Max 2.0 petrol Ecoboost SCTi (203PS version) and need to know what is the correct size for the front brake discs.
Confusingly, some websites selling car parts tell me it's 300mm diameter, others 316mm.
I think the 300mm is for diesels and I think, also for the older pre-ecoboost/non-turbo petrols. The 316mm seems to be for the older 2.5L petrol Turbo.
Does anyone know better?
