Or alternatively of you don't want to bend it, you can trim the outer edge off the dust shield.

I thought it was a straightforward fit 4th gen rear discs on a four stud 5th gen ?

All sorted now, front discs fit lovely and calipers are on too. Taken some photos and going to compile all the information into a guide at some point once the car is all sorted.

I haven't yet, going to have to order some 5G ones if I can, rear discs for the 2.0 are both insanely expensive and very hard to find.

Here is the difference between the two discs. New 4G on the left and my old 5G one that came off the car on the right. First thing is the retention screws are in different places but that's not a problem as they're not a necessity just nice to have. The main difference is this small ridge as I said earlier. It's right at the base of the disc hub but doesn't exist on the 5G disc, it means the disc doesn't clear the hub on the car. I could try hammering it on?

Ah a chamfer on the back of the centre bore.

Pretty sure that is meant to be there on a 4g rear disc too, so it may be you have a duff set?
I will check a set next time I'm at the barn...

What does the hub look like in that area, on a 5g?

The problem is they're all so expensive! Only ones Euro do areover £70 for a pair from ADL...looks like I may have to bite the bullet though.

That is what I suspected but I've emailed them and they're sure it's supposed to be there. I'll get a photo of the hub in the morning but I'm sure they're the same.

I haven't seen anyone else do it but the general consensus I got was that all rear brakes were the same from 92 onwards which should mean the only difference in discs would be the fitment.

Here are a few photos of the hub, as you can hopefully see it doesn't quite fit all the way on which is why I think it is that small ridge on the inside of the disc hub.
