Z4 3.0 rear brake disc not fitting!

[outdoormax]

has any one had problems with aftermarket rear discs for 03 3.0 z4. I have ordered some from Interparts they arrived and they did not fit! I spoke to the guy he said there are only 2 types and as mine are the 3.0 versions ventilated and 294mm, I thought he had just sent me the wrong discs, so I then got some more sent using the reg number from euro parts.. and they don't fit they are the same as Interparts ones. I have spoken to BMW and they say there is only one type for this car as well. The reason these do not fit is that the offset for the disc is not big enough resulting in not being able to get the wheel back on! any one got a suggestion other than going to BMW? or had this problem?

There are two part number used on the 3.0 Z4, depending on the date - maybe the aftermarket ones are using the later one?

Up to 02/2004: 34216754137 (only used on the 3.0i)
From 02/2004: 34216766219 (used on later 3.0i and 3.0Si)

Both are the same size disc though?

thanks again brilliant! I have also just purchased a pair of OE discs from ebay (correct numbers) for £65 delivered! So very pleased!
