the fronts are coming up as 288mm confirmed but i cant seem to find the mm length for the rears its not coming up, i was hoping you guys can help, what is it size for the rears, i dont want
to buy the wrong ones there is 255mm 260mm and 282mm?

My 2.0TDI Sportback 2006 is using 288mm Front, 255mm Rear, so I suspect yours is the same.

mine also are 288 front and 255 rear...
i have the grooved brembo max discs on them which will be coming off the car very soon and up for sale as i am upgrading to larger brakes
