Hi guys does anyone know what the size of the rear disc is on a mk8 tourer? It's giving me 2 options 282mm or 305mm, or am I going to have to take it off to measure it? Cheers. 

Hi.....welcome to the Forum

 

That's a tough one as 23mm is not that easy to determine when looking through a wheel.....I would probably remove the wheel at least and try to measure it.

Sometimes the difference is whether it is 4 stud or 5 stud fixing though so worth looking again at the fitment details which might show the difference between the two
