Brake disc size

[Olly2905]

Hi all,

i have a 2013 a5 3.0tdi quattro 

im looking to replace front and rear discs. There are multiple options in sizes , im lead to believe that the fronts are  320mm and the rears 300mm is this correct ?

Welcome Oliver and thanks for joining. 
Where are you looking, to come up with your multiple choices, and what band/s are you looking to buy?

Would be be right in believing you will be renewing the pads at the same time, and again, have you decided on what brand you are going to use? 
Kind regards,

Gareth.

Apologise mate, 

been out of country due to work and have been unable to take the time to reply. 
 

I bit the bullet and on a size and ended up being the right ones. I bought 320mm front M-tec c hook front discs and EBC yellow stuff pads. Same brand and design for both on the rears but they where 300mm discs
