Seconding the recommendation above regarding Anderson Composites—their quality is usually the benchmark, but honestly, I've had some mixed experiences with the aftermarket scene lately. I've spent a ton of time researching the market for my own V-Series, and unfortunately, the "gold standard" is getting harder to find because so many vendors are just white-labeling the same stuff from overseas.

I totally agree that the piano black is a nightmare, but I'd be super cautious about full replacement pieces for the interior. I've seen some high-end kits where the clips don't line up perfectly, and then you're stuck with a permanent rattle in a $100k car, which is just painful. If you're looking for that deep OEM 2x2 twill look, definitely check out RPI Designs Carbon Fiber Center Console Trim or the APR Performance Carbon Fiber Front Air Dam if you decide to go exterior. APR is legit because they actually use a pre-preg vacuum process, so the resin-to-fabric ratio is spot on, meaning it's WAY less likely to yellow or delaminate compared to the cheaper hand-laid stuff.

Actually, one thing people forget is that the factory CF1/CF2 weave has a very specific gloss level. If you mix brands, the clear coat depth might look different in direct sun. Id probably stick to one vendor for the whole cabin. Ngl, it’s a bit of a gamble, but going with a company that handles their own manufacturing like C7 Carbon CT4-V Blackwing Rear Spoiler usually results in better fitment than those random drop-shippers. Just make sure you ask if they use UV-stable resin... seriously, dont skip that step lol. gl with the build!!

In my experience, you definitely get what you pay for with carbon, and since you missed the factory packages, you gotta be careful with the weave match. I went through this exact same thing with my Blackwing cuz the piano black is literally a scratch magnet lol.

Here is how I see the top options right now:

1. Savage Cadillac CT4-V Blackwing Carbon Fiber Interior Trim Kit vs TapTes CT4-V Carbon Fiber Replacement Parts

* **Savage Cadillac:** Honestly, these guys are the gold standard for us. It's real 2x2 twill and the clear coat is super deep. I've had their pieces for a year and no yellowing at all. They do actual replacements, not just tape-on stuff, so it sits flush. It's pricey tho, easily $500+ for the console area, but the fitment is 10/10.
* **TapTes/eBay stuff:** Basically just thin overlays. They look okay from five feet away, but you'll see the edges of the original trim underneath. Plus, the resin is usually cheaper and might haze if you park in the sun too much. Save your money and skip these for a car this nice.

2. Extreme Online Store CT4-V Blackwing Rear Spoiler Carbon Fiber

* **Pros:** This is a great middle ground for the exterior. It's a full replacement and the weave is actually a decent match for the OEM CF2 look. Way cheaper than buying the part from a GM dealer.
* **Cons:** Install can be a bit of a pain if you're doing it yourself, gotta be careful with the adhesive removal.

Best choice? Go with Savage Cadillac for the interior bits if you want that factory-integrated look. Its highkey worth the extra cash to avoid that 'stuck on' look. Good luck with the build!

> "I’m looking for real, 2x2 twill carbon fiber that matches the OEM quality—something with a deep clear coat and perfect fitment."

be careful with the super cheap "real carbon" stuff you see on random sites. honestly, the resin quality is usually trash and it might yellow in the sun after like 2 months... since you want value, i'd suggest looking for vendors that do core swaps. you send your piano black parts in and they wrap them in actual 2x2 twill. it's usually cheaper than buying full dry carbon pieces but fits perfectly! gl!

In my experience, you gotta be super careful about interior bits that could shatter in an accident. Cheap overlays are basically shrapnel if an airbag goes off. Honestly, I'd skip the stickers and look at the Anderson Composites CT4-V Blackwing Carbon Fiber Rear Spoiler. It's a full replacement and much safer than tape-ons. For the cabin, maybe check out APR Performance Carbon Fiber Dash Trim if you want that OEM-plus feel without the yellowing risk. Safety first, man! 👍

I went through this last year... basically had the same exact regret after staring at the piano black for two weeks lol. Since I'm a bit of a nerd for specs, I actually measured the weave on the factory parts I did have. Most aftermarket stuff uses a 3K weave, but the resin density is where they fail.

In my experience, TapTes CT4 Carbon Fiber Center Console Overlay was okay for a bit, but I eventually swapped it for Envision Carbon CT4-V Blackwing Replacement Door Trim because I wanted that true OEM depth. Honestly, the biggest technical hurdle is the UV inhibitor in the clear coat; if they don't use a high-solid automotive clear, itll yellow in 6 months. I finally settled on Savage Cadillac CT4-V Blackwing Carbon Fiber Dash Replacement pieces and the match is basically 99% identical to the factory CF1 package. Definitely worth the extra cash over the cheap stick-on stuff.
