CSL Diffuser options

[elrichmeister]

As much as I prefer quality parts that last, the idea that the price difference between the "best" diffuser parts and a plastic knockoff is an entire set of tires gives me facial ticks.

This is an unstressed component, which in my mind is 100% cosmetic (there's no real amount of downforce change by swapping to the CSL style). I do prefer the look of the exhaust tips being tucked under the protrusion of the CSL style part, but I don't really care that much about the exposed carbon (I have a black car that doesn't show carbon that well anyway). I found the turner ABS piece as an option, but from the pictures it appears that they tried to give it more aggressive styling which I don't like.

Is there basically a CSL plastic rep part that will fit and cost $1000 less than vorsteiner/MEC?

I have ABS plastic turner diffuser on my car. Fitment was good and looks are subjective but i do like how it looks. However the mounting tabs are very fragile, first one they sent most of the tabs were broken, but they sent out a replacement with tabs intact.
Was an impulse buy at such a cheap price, in the future ill invest in a better diffuser.

I bought a cheap one and it fits pretty meh. In the end it was probably $850 for the diffuser and paint. So not exactly "cheap" nor does it look great.

Buy once, cry once.

All the eBay ones are made by the same manufacturer from the same mold and that mold has quite a few noticeable issues.

This is a piece where I would go for a high quality rep like MEC or stick with the stock diffuser. Since this is a part that rarely gets damaged (unlike front bumpers and splitters), you can list it for sale if you change your mind or if you want to go back to stock.

There's a reason why the eBay diffusers look terrible.

I'm sure you can figure it out.

It's a lot for a diffuser but you really wanna throw a part on your car that looks crooked all the time?

Folks say they don't notice but that's a lie.

Not really.

Anything cheap fits like shit.

You can gamble with ebay ones, but you may or may not get lucky... and even the ones that 'fit' need massaging.

Unfortunately this is one of those things where you get what you pay for.

anyone know if the happybuyitnow / euromotorsport CSL style diffusers are typically FRP backed and only carbon topped in the center portion if painted?

[BlueBimmers]

You are correct. Noticed rubber hangers are shot. Next DIY! ;-) Or I'll just have shop do it. Looks like diffuser does not need to come off to do job, which is a positive.

Finally got installed. Really happy with it, there were some fitment issues.

Diffuser looks great. Any adjustment on the AP muffler? It needs to come up quite a bit, especially the right side.

Picked up a Vorsteiner for fair price from enthusiast who sold his E46. When I get painted and installed will report on fit.

[tnord]

it does help, thank you. It seems like the things I'm looking for would direct me to one of your options, thanks for the effort to get them created and offered.

[Epoustouflant]

I've ordered from this seller and they are top notch in terms of quality. I would imagine this would probably fit the bill.

This is the Genuine BMW unit, expensive, and not without issues. I can source it as well for those that want the Genuine BMW factor.

Well that has to do more with how detailed the buyer is with looks. Sure some of those aftermarket can look good. But there’s a bit more to this than just a fitment replica. Many of these China replicas aren’t true OEM CSL part copies. They lack the curve and shape at the bottom edge of the CF by the tips(they’re more roundish).

Also having seeing this first hand, the CF weave is rather poor. The CF pattern doesn’t match up with another sheet they used, also and can look twisted going around curves. Then they might only have 2x2 weave and not 1x1(OEM). Lastly I’ve seen some look good for like 2-4 years then the clear of CF starts to haze or crack. For a short term owner this isn’t much an issue.
Having said that many might say it’s low and some of these things can’t really be seen. And are fine with that. So for these people they are fine with these deficits. Which each person weighs pros/cons vs pricing. Others it might bother them and are detailed oriented and willing to pay more.

Agreed on all the above - thanks for sharing.

As long as people know what they're buying into, I will never judge anyone's decision making on builds.

^^ agree with everything old///MFanatic said.

Before this turns into pissing contest / EuroConnex slam, let me add to my original point.

It had been a while

I do have two observations to make:

1. The not-so-subtle insinuations are usually from those that I have not dealt with.
2. Facebook Groups and Forums have much less participation from brands and shops compared to yesteryears. This forum is notoriously free for "sponsors" if they provide value - a great policy.

My stance on these beauty covers will remain the same. These things are nearly 0% functional and nearly 100% cosmetic. Being so low to the ground, as long as it looks great and can be made to fit great with some effort, I'm a happy guy. For me, this is one of those products I simply cannot justify spending $2k or more on. For others, I completely see where plunking down that kind of cheddar makes sense and I'll not fault anyone for it. There are plenty of other products EuroConnex curate that I would happily plunk down $2k for though. It's a matter of what's important to you and what isn't.

As we exchanged via DMs - I can't ever be judgemental of any conscious decision making.

Going though the stupidly expensive process of fully restoring, color changing and upgrading my E46 to CSL spec, I can only attest that there is no perfect build. Compromises have to be made, and anyone taking on this endeavour understand the pain that it is to know where exactly they were made - but it's nothing compared to the pain suffered by our wallets.

If he makes a buck or two in the process, great.

There is something about some car communities that make them allergic to anyone doing well for themselves - or the perception of it, that E46 is killing me!

Value should generate profit. Profit should bring in competition. Competition should move us forward. I can only be glad companies like MileEnd are getting back in the game and Vorsteiner as well. A rising tide lifts all boats.

Matt works hard to get this group of enthusiasts really interesting products that would otherwise not exist. Or he gets deep discounts via coordinated group buys. I think he does good by the community and am happy he's here and stoked he's curating unique stuff for us.

That means a lot as you know - I appreciate you for taking the time to make that statement, noise is loud.

I'm in on paying for quality 1x1 weave, clear that won't yellow, a part that fits, not china, and a 1:1 replica part. I'm not a short term owner, I bought this car in 2010. But do we know which option meets all of these conditions?

From the variables you laid out, the best options are the 3x I previously listed.

1. This one is most popular because it strikes a balance between price, 1:1 replica, pre-preg carbon work, and paint service. It's not been without faults in terms of paint quality and the ready-to-spray primer and professional fitment by a body shop is my recommendation for those that want it perfect. The tabs may some slight trimming to clip in depending on the condition of your brackets.
2. This one has the best carbon work around but there is no paint service, nor primer. I can import these duty free from Germany and get them painted at the shop before sent out to you. I usually ask for your gas cap to be sent over for a perfect paint match considering these cars are old.
3. The Genuine BMW unit is most expensive and has the "original" factor going for it. Carbon work is great and clear coat is hit or miss.

I hope this helps! Feel free to reach out via DM here, on IG or via the site. I can take you the options in further details.

Reach out to Matt. That's really the only one that meets all your criteria. They seem to be really nice pieces.
