CSL Diffuser options

[antknee]

Wow that looks terrible.... i guess lesson learned don’t get a non-happybuyitnow one from eBay. There doesn’t even look to be any tabs or mounting options for the top portion of the diffuser either. Thanks for being the guinea pig

And be aware that all things are not great from happybuyitnow. I bought a gloss black front lip from them. The fitment was pretty good so I did install it but the gloss black "paint", if that is want you to call it, was just horrible. Horrible. Not a big deal as I immediately stripped it and repainted before install.

Just received my Happybuyitnow diffuser today, for the cost the paint/weave are pretty good, the fitment is a 7/10 in my opinion.
It fits flush in that there isn't any portion (like the middle) that sticks out anymore than the side portions. The main fitment issue is the width, this diffuser is a bit too small width wise.
If I move it all the way to the left I have a noticeable gap on the right and vice versa. When centered there is a larger than factory gap on either side but acceptable with cost in mind in my opinion.
I should have taken photos of the metal mounting strips before I installed it, basically instead of the factory molded in clip type pieces on the OE diffuser, this diffuser has little metal straps that insert into the mounting slots and then you bend the metal strips down to lock it into place.
The outer most metal mounting strips were put too far out to the edges of the diffuser and thus they are not able to go into the outer most factory mounting points on the vehicle, they are useless.
This isn't good, but that being said even without them doing anything once the lower plastic push rivets are in place it seems solidly mounted, I don't think it's going anywhere.
How long those metal strips will last in the way of repeated dismounting/mounting time will tell.

All in all and taking cost into the equation of course I am satisfied with this product, so far.

This first photo shows the metal mounting strip, and the red arrow points to where it should be, this is the case on both sides.

Here are a few ground level shots:

(I feel like this gamble may have payed off, but time will tell..)

I think it looks and fits great. My tekarbon one has the same metal tabs and I’ve removed mine about a half dozen times and still no issues.

as far as the tabs on the far end, i bent it like the highlighted yellow

Nice to hear, I eneded up doing the same things with the end tabs and at least they do grab something a little bit bent sideways.

Looks great

I've been looking to pick a CSL rear diffuser and was planning to go with Mile End Composites but it looks like he's unable to continue to produce these/NLA (based on his most recent IG comment).

Other than OEM, what other options has everyone been satisfied with, fitment/quality wise?

Mile End Composites are local to me (Montreal). I will have a chat with them.

Last I heard they aren’t in production because their mold gave out.

Post #54 is referring to happybuyitnow.
saw posts regarding the tabs dislocated, sent an email informing them of the issue.
See if it does any good.
Will let you know in a couple of months.....

Last I heard they aren’t in production because their mold gave out.

They need to make an aluminum mold if that's the case. They probably didn't because of low projected ROI. If we can get them volume, I don't see why a CNC'ed mold wouldn't make sense.

That's where we can leverage the Connex to get this into production again.

Well, I will have to say "holy crap", ordered my diffuser from happybuyitnow on the second of this month, and it just arrived now (the 9th). Quality looks really good. Color looks a real good match(Mystic Blue). Don't know about fit yet, will attack that within the next couple of days.
Have to say again, so far impressed !! Live on east coast, delivered in fairly sturdy box, with sufficient packing inside.

For post number 51 you could always fiberglass your own little metal tab in if you wish to
