A3 Sportback PD170 Front/Rear Discs

Hi Chaps,

I'm getting conflicting info from different suppliers regarding what diameter front and rear discs are on my A3.

Suppliers are saying 280mm, 288mm, 345mm for the fronts and for the rears the options are generally 255mm, 260mm, 310mm

Not one of the suppliers will commit to ensuring the discs they supply are the correct dia. Short of removing the actual disc and taking a measurement I'm stumped.

Any ideas?

BTW the car is a pre-facelift PD170 S-Line (FWD)

Thanks in advance,

Thanks,

great help, 312mm fronts and rears 255mm
