I've got an alpine white e46, your temping me to scoop this bad boy..

I have a few units in production for inventory. They are primer version but can be spec'ed to color match.

Do you have pics of the new drilled holes? I'll see if I can document this as well.

I don't unfortunately, and I don't think I'm going to pull it off now lol.

Basically I just sanded down the upper tabs like you documented, and then on the bottoms I just pulled it down tight, and wherever it lined up I just sank a new hole with my drill.

Much like this


The top tabs gave me more trouble than the bottom. The second to the outer most tabs just didn't want to clip in no matter how hard I pushed. I had to pull it off and sand them down like 3 different times.

Dang - you nailed it. The side gap and curvature alignment looks perfect from here.

Thanks for the follow up on this.

More pics. I ordered brand new clips for the bottom, and I did eventually get all 6 clips in. I had to drill 4 new holes, I only used the 2 middle factory holes.

I personally think fitment looks factory, IDK that I see any gap at all. Just posting for anyone that is worried about fitment, if you know what you are doing you can get this to fit like a glove. Just don't expect it to bolt on and be perfect.

Thanks Matt!

I love it too.

[Epoustouflant]

Glad to hear you got it to your liking - I still can't get over how forged carbon is excessively subtle, ever against AW. It was a bold decision and you pulled it off.

Both Tbone and I had to drill a new hole on the passenger side outer edge to pull the diffuser down. If I used the factory hole it was like this but even worse.


So it's possible that pulling it down at the bottom caused the upper part to form a gap. I really don't notice it in person.


You can tell in this pic, right below the tow hook it's not completely flush with the bumper, that's the tab I'm talking about sanding down. It's like that on both sides, maybe that also contributes to the gap.


Honestly I've seen way way worse, I don't consider that a gap even.

Thanks for writing your impressions on this diffuser. I noticed the gap in earlier pics but this one really caught my eye. The gap at the top is definitely noticeable.

If you look at the straight photo of the diffuser and bumper, you will notice there’s not much gas towards the top left but the gap gets wider as it runs along the passenger side.

Final fitment.

Maybe.

TBH it could be pulled off again and i would hit the third tabs in from the end with sandpaper to make the bumper 100% flush, it's lightly bulging out where those tabs are. I'm tired of messing with it though, I'll probably just leave it. You can't tell unless I point it out.

To get it to sit like this, I had to sand down multiple upper tabs, and drill 2 completely new holes on the lower outer edges to get the diffuser to tuck in tight, the factory holes made it uneven. As it sits, only 5 of the 6 bottom clips are in, the passenger inner clip doesn't line up at all with the bracket.

Overall am I happy?

Pretty much, it fits really good now, IMO, and the quality is on par with the price.

Would I purchase again?

Yes, because Matt is great to work with, and it ended up coming out great, despite it needing to be massaged.

FWIW this is on a 54K mile car with 0 zero accidents on Carfax.








The thing that is now driving me crazy, is... I never noticed before but my damn Dinan muffler is crooked. The diffuser really makes it noticeable lol.

Diffuser is on... for the most part. I need to do some final tweaking.

Let's just say I didn't have as easy of an install as Tbone. I'll probably write up a review later.

It does seem that mine will eventually line up better than previous posters ITT, but it was most certainly not a plug and play affair.

FWIW the paint on my diffuser seems to be pretty flawless for the most part, paint match is great, and there's very few imperfections in the fiber. Definitely no pin holes. The quality of the part is high end, that's not up for debate.

Fitment leaves a bit to be desired, and that's being nice.

Here's a better shot without the flash, this is what it looks like normally.

I can't see it for some weird reason.

[9kracing]

I finally get to see it Looks much better than I expected. Proper looking forged carbon is a rare thing.

I am interested in either!

I'm actually just about to launch one for 10x minimum units of the 1:1 - let me see if I can include the GT.
