Brake disc sizes

Realoem says 300mm diameter front 294mm rear so was just about to order when I noticed an ebay seller is suggesting that I may have 286mm on the front?

Is this possible? Or is he just a knob?

3.0i front are 300mm

3.0si front are 325mm

2.5i front are 286mm

3.0i & 3.0si rear are 294mm

So if you have a 3.0i your all good
