Mk3 Focus TDCI Zetec S - Brake Disc sizes

Hello! 

I just wanted to see what the standard diameter of the front brake discs are. I’ve tried strolling through the forum but can only find mark 2 details. 

Ive got 18” alloys (optional extra w/ ford) I’ve tried having a rough measurement (using two straight edges and a tape measure) and think the 278mm ones would be a rough estimate. 

Any clarification would be awesome!

 

thanks

    I'm fairly sure the mk3 Zetec S got 300mm discs front and disc rear even on the 1.6.  Measuring should guarantee it though, I don't see that you could be 20mm out?

    I believe if you have rear discs it will be 300mm front, 270mm rear

    Drums you will have 278mm at the front
