Hi All,

What material have people used when installing the M Performance Rear Diffuser?

From the manual:

Only for cars of a light colour
Blacken the area (4) of the car at the rear right using
suitable means.

Thanks

I haven't actually done so on mine yet, but I'll probably just clean the area and use some black tape when I get round to it. That or some plastidip/something else non-permanent

What part are they referring to?

Nothing needed blackened on mine.

Sorry i think this is a 4 series only issue, the 3 series diffuser is not as good

Lol.

Does it mean behind the little grilles on either side of the 4 series diffuser?

yes but only the right side.

I just left it. You don't notice anything with the black grill in place.

On a light coloured car you do as you see the battery compartment on the drivers side. I applied a piece of matt black sticky backed plastic.

Black vinyl wrap will be your best bet.

Black gaffa tape from poundland or home bargains for 80p a roll
