A very large box was just delivered. I will open it by the end of this weekend and post some photos. I know you guys will easily figure it out before then.

Many thanks. Love what you are doing with the car... makes we want to go buy another e46 and do something similar!

Is that new upper trim piece titan shadow finish? How well does it match your lower trim piece?

In early November I ordered a Vorsteiner V-CSL diffuser with a lead time of 8-10 weeks. I went with Vorsteiner for a few reasons, mainly being the design. It seems to be the only replica of the CSL diffuser that includes the ridge that lands between painted and unpainted portion. The upper left and right corners are far less rounded than most replicas, and that should eliminate that unsightly gap that most replicas have. Vorsteiner is 30 minutes away from my house and I was able to pick it up to avoid shipping costs and see the product in person. I do want to mention the customer service I received both online and in person was outstanding.

I haven’t had time to do a test fit, but my initial impressions are really positive. The weave is perfect, there doesn’t seem to be any weird misaligned patches near the exhaust tip area like you see on other replicas. The clarity of the finish is great. There was a tiny bit of leftover polish residue but I’d rather do a little bit of cleanup than receive a part that wasn’t properly corrected. The mounting tabs look really solid and beefy. It almost looks like they put a bit of extra epoxy/resin on the tabs so that they could shape the tab for better fitment. There is a metal badge with Vorsteiner's logo double sided taped to the diffuser. It's a really nice little badge, but I'm not sure why anyone would want that on their diffuser. Luckily it looks to be easily removable. It is really a non issue but I thought someone might ask about it. Hardware is included, and weight is 1lb 4.8oz

Here are some photos.

Do you happen to know the PN for that upper trim piece? looks incredible

It is black plastic, it does not have any paint, coatings, or finish on it as far as I can tell. If you need a visual reference, i'd say its about the same as your the plastic on inner door handle. Satin black with a tiny bit of texture.

Blank upper steering wheel trim and refinished lower steering wheel trim installed. Loving this streamlined and driving focused setup.

Man I wondered who picked that trunk up! I unfortunately saw the FS ad too late. Glad its going on a great build though

Continuing on with the theme of buying parts when you can, not necessarily when you want.

Just before Christmas someone posted a reasonably priced (for 2023 market) OE CSL trunk less than 40 minutes away from me. I drove down, confirmed it was a genuine BMW part by inspecting / comparing it to resource images I had saved, then weighing it (yes, I actually brought a bathroom scale).

The seller said it had sat in his garage since 2019, and by the looks of it, he was being honest. There was an incredibly thick layer of dust and dirt on it, and the paintwork had a good amount of scratches and chips. I wasn’t concerned with the paint condition, as it was going to get repainted regardless. Most importantly, it was solid, no structural damage, broken corners, modifications, etc.





I had no doubt it was the real deal and I picked it up as an unexpected Christmas present to myself. I cleaned it up, took a cheesy photo under the Christmas tree, then packed it right back up for storage.




Although the actual paint and install won’t be happening for a long time, I am already preparing for the install by buying all new hardware, pre fitting accessories, and creating the license plate lights wiring harness. Every part on the trunk will be new. I’ll be documenting the entire process and creating a comprehensive DIY. For now, the trunk will sit in storage while I continue on with the interior.

While doing research for the CSL install, I found no comprehensive DIY for this project. I had to pick through various forums, YouTube videos, and random decade old PDFs to piece together some sort of a tutorial. I decided that I was going to take on a clear and comprehensive DIY that could be used by others in the future. Once it’s finished I will host the PDF on my website and give it to Karbonius so they can provide it to future customers. For now, here’s some info and photos of the install.







Here’s everything that was permanently removed.

First of all great build, really love the attention to detail. Do you feel that the sound deadening is necessary on the back of the carbon interior panels with the vapor barrier already sort of acting as some of it. Reason asking is because I have a set of panels that are waiting to get installed. Kind of bummed that I didn't as KARB to see if they can do brushed door handles since I have brushed aluminum trim as well.

That’s a very fair question. In terms of adding sound deadening on the back of the carbon panel to block/reduce road noise, it probably makes little to no difference.

I installed the sound deadening to change the way the panels felt, not to reduce ingress of noises. With the sound deadening on them, they have a lovely solid feeling when you interact with them. Whether you are purposely tapping on the panel, or incidentally knocking your knuckle as you grab the door handle, they just feel sturdy now.

As you know, the Karbonius panels are made to such a high standard and are incredibly light. The flip side of that is they have a slightly tinny feeling when you touch them. With the sound deadening, you are literally only adding ounces of weight while dramatically enhancing the feel of them.

Have you driven the car yet and observed any change in cabin noise?

Drove it to a local cars & coffee meet and did not notice any dramatic increase in noise with the insulation removed.

I did notice that the car smells far less like an E46 M3 now. The insulation has been out for a few weeks now and the interior has definitely lost some of its iconic smell. It’s been referred to as “crayon smell,” but I personally never thought it smelled like crayons. Regardless of what it smells like, it dramatically diminished.

I haven't driven it yet, but when I do I will listen and report back. To be honest though, I've driven this car so few miles that I'm probably a bad judge of what the baseline noise was. Either way I will let you know.

If you are preparing to do your install, my comprehensive DIY will be posted within the next few weeks. It has pretty much every detail you could want.

Thank you! Yes, I'm preparing to do the install as well. Looking forward to see the detailed DIY post.

Amazing build!! Can you share the exact details on the hardware used for the CSL door panels?
