^^ easiet way is to check what calipers you have if you have LUCAS or GIRLING calipers then you have 280mm brakes and if you have ATE calipers you have 288mm brakes
Cheers for that, confuses the issue more for me, and in theory disreputes the quote i copied, they were Lucas calipers, but when I measured they were 288 but as I said that's going over the centre of the disc, I'm gonna get some vernier calipers on em so I'm def sure when I buy em.. 
if its lucas calipers they are definately 280mm and you have just said that when you measured them you had the tape bent over the disc so it will read bigger than that the disk actually is
I agree, but it was in the high 290s and it only bowed a small amount so basically, im gonna get some vernier calipers on em, cos if I go by your method they are 280 and if I go off the fact its a 96'on and the abs ecu location in the engine bay they are 288, so wheel off again at weekend..

thanks all
