A4 B8 SE to S- line bumpers. Can't see any difference??

I quite fancy upgrading my bumpers to s-line spec ones as they seem really cheap to buy second hand of e bay ( front ones anyway).

However I'm really struggling to see the difference between SE and s line front bumpers? The rears seem the same other than a different style diffuser?

Maybe I could get away with just a new s line rear diffuser unless anyone knows different?

I have managed to find some genuine s line side blades for £100 so seems a shame not to do the bumpers aswell.

Thanks.
