Brake Disc Quick Question

Basically i have had a few issues with a dealer fixing my brakes lately, anyway to cut a long story short i have been told that i definatley have the AP racing disks on for the Exige but that they are the same as some Elise models. Is that true? I just wondering if there are more than one genuine Lotus Exige brake disc avaliable (ie motorsport upgrade) and have i got the right ones fitted

Got a photo or a part number?
