How to remove the rear diffuser?

motex · 08-28-2014, 07:35 PM

Hello,
Anyone with DIY instructions on removing the rear diffuser on the M4, I want to paint it in black (plastidip just in case I don't like it) but wanted to do it right and not brake a thing.

Thanks in advance!

4 8mm screws at bottom, hinges out of place. Very simple.

agree this was super easy, even I was able to do it! And wow what a impact it makes to the overall appearance of the rear of the car

2 fast and 2 easy....lol

Even the bolts were too loose, have to be carefull not to use too much torque when replacing
I think next step will be paint it in satin or glossy black
Have a great weekend!

Looks great man, I'm going in the same direction, don't want to spend on CF, also thinking on the CF rear spoiler which looks great on white
Nice ride man!

@filip75 that looks good. I can't decide if I want to do this or get the CF diffuser...

Be sure CF diffuser will look neat, not just because of the CF but the shape also is more agressive, I think is a matter of spending a lot or a few bucks

Yeah... also want to see the aftermarket diffuser options when they start coming out. Normally I wouldn't buy aftermarket CF parts (bad experience with last car) but this diffuser is on the ass end of the car and will be hard to see close up so I thought this or wrapping it would hold me over until then...

You can't be more right here! M4's are so new.... it will be a good idea to wait some time until aftermarket parts start to show everywhere, probably there will be lot's of good choices out there in the coming weeks

motex, does the heat from the pipes cause any problems with the plastidip melting? Something to maybe keep an eye on...

motex · 08-30-2014, 10:26 AM

No damage yet, not a big fun of Plastidip, but is a good temporary solution for testing.
I did it just to see if I like the final look, I will paint it black but still not sure if glossy or satin black.

I ended up buying a can of plastidip and spraying my stock diffuser. After attaching the spoiler, I needed something fast since a the white diffuser wasn't doing it. Everything turned out great... it matches the plastic trim things on the sides of the bumper. After reading that the foot-trunk thing doesn't work with the M-perf one, I will probably just leave it like this for a while. $7 vs $1000. Lol...
