Carbon Rear Diffuser

CrossyN · 04-30-2018, 01:43 PM

I've just ordered the carbon diffuser from carbon wurks, £350 https://carbonwurks.com/shop/by-cate...rear-diffuser/
It says in stock but it isn't, there's a 2 week wait, but worth it I think, they sound like they know what they're doing so it should hopefully be decent quality.

I'd still recommend the one I posted at the start of the thread if it still works. More than 12 months on and looking as good as day one.

I'll take a look shortly and see what's on EBay still

I had one and sold it on to a forum user, it was nice.

I have just waited 2 weeks for mine from Carbonwurks. Mine arrived today, I will get some photos taken.

Here are a few photos, fit is very good!

Slips · 05-01-2018, 02:39 PM

Looks like it’s a very good fit from those photos.

Mine is Sakhir also.

Are you pleased with the new look from the rear with the carbon diffuser?

Yes very happy with it, just need black exhaust tips now and front carbon splitter.

Fitted it yesterday, nice and easy

Do you have a link and price for this please buddy? (Apologies if posted earlier, did a quick skim read and didn't see it).

It's gone up a bit. Blame Brexit

Ordered one of these last night, will let you know what I think of the quality/fit etc. Was tempted by the CarbonWurks one as it looks better in the pics but it’s almost double the price.

I just fitted my rear diffuser from Carbonwurks. Once it's on it looks the doggies danglers, but the fit wasn't great for me. I had to really pull hard on one side of the diffuser and essentially slightly bend it to get the screw holes to line up, they were roughly 1mm out which doesn't seem a lot but it is when the screw won't go through. Also when looking at it from ground level there's a slightly larger than I would like gap between the top of the diffuser and the bumper, but you can't see it from normal eye level so that's fine.

Overall, well happy with it now it's on! Getting the original diffuser off was definitely not as easy as the various guides suggest it is!

Looks lovely! Do you have the MPE as well?

Negative, it's the CP exhaust with the $250 carbon tips from Alibaba!

I personally wouldn't spend that on tips alone! Fair play to you though bud, they are very tasty.

CrossyN · 05-24-2018, 11:21 AM

Well considering the cost of the full MPE I thought it was a steal as I'm 110% content with the CP exhaust! They're quite popular, there's a massive thread on here full of people who've bought them.

It was £350 just for the diffuser which is arguably less noticeable and just as ineffectively functional as the tips, but that M tax is strong.

Slips · 05-25-2018, 02:21 PM

Ordered the eBay diffuser on Sunday eve and it arrived today Friday.

Not got any pics yet as car is in my garage but all the mounting holes lined up ok but I couldn’t get the two middle screws to hold properly due to how short the screws are and the extra thickness of the the CF diffuser mounting tabs. Doesn’t seem to make any difference with screws out as diffuser is held in place fine with the two end screws and tabs at the top.
Fit looks ok but I would need to compare it side by side with the MP one.

Will get the car out tomorrow and have a good look at it and take some pics. BTW the weave looks fine to me.

IM2C · 05-28-2018, 10:42 AM

Got mine today. Lightning fast shipping from Taiwan. I had a bit of a fitment issue due to leftover epoxy on the inside. CF weave is spot on.

IM2C · 05-28-2018, 08:10 PM

*Foot trunk release feature still works as long as you make contact with a diffuser. Watch the video.*

Shortyy · 05-30-2018, 04:15 AM

Hey lads..

Are people still recommending this diffuser?

http://www.ebay.co.uk/itm/1916685043...%3AMEBIDX%3AIT

The fitment sounds good from what a few on here have said, how is the weave compared to the carbon roof and other M performance carbon parts?

Think I’ll give it a whirl providing this is still the one to go for.

That's where I got mine from and still very happy with it 18 months on.

Slips · 05-30-2018, 12:58 PM

Here is the Ebay diffuser, looks ok for the price. I'm sure the MP one is better.

Really needs some Cyba exhaust tips now.

My boot release still works with leg as well.
