Rear diffuser help

[A3Bash]

I want to replace the current part...

With the S-line diffuser

Would I need to change the bumper or is it a straight swap? Thanks

You need the bumper for it to fit perfect however the later diffuser can be forced to fit your older bumper with a few adjustments to the clips/mounts. Once this is done it does fit flush but for me, it doesnt look quite right unless you have the bumper to match.

I thought with it being a 2 section bumper then the lower section would fix onto the origional upper?

You would be right in assuming that but if you look at the red cars bumper, its a lot mpre straight and doesnt have the ridge in it that the silver one does. As a result, its a slightly different shape
