Who knows the differences??

I'm just after the black plastic one to fit as it comes, not primed or carbon.

There's this option:

....And there's this option (item 9):

This is one part, called a 'diffuser kit' - it says primed, but is it different to to the one listed in the first option?

[Anneka @ Sytner]

They're both the same.
The first one is just the back end of the second one, and the kit includes the Performance rear bumper.
If you order item 9 on it's own (which is the same part number as item 2), you can fit this into the Performance rear bumper or the M Aerodynamics rear bumper.

It comes in primer.

Cheers anneka.

I had heard people talking about fitting the black plastic one rather than a primed one that needed painting.

I don't want a painted one.

Mike, pic of the diffuser (E92, E91 might vary?) here:

The black plastic centre section is not designed to be painted, although I guess you could if it was prepped properly.

You can also get the centre section in CF on the tourer and saloon, but I realise that's not what you want.

Some people have mentioned cutting in certain places, but I never had to do any.

Thanks Ian,

I think the e90/91 is different to the coupe, but I remember Yahoo fitting the unpainted plastic one on his tourer.

bit more investigation needed....
