Which carbon fiber upgrades are best for CT5-V Blackwing?

Question

I recently took delivery of my CT5-V Blackwing, and while the car is an absolute beast, I didn't opt for the factory Carbon Fiber packages (CF1 and CF2) at the time of order because of the constraints and added lead times. Now that I have the car in my garage, the exterior feels like it’s missing that aggressive edge, especially around the front splitter and the rear spoiler.

I’ve been looking at some aftermarket options like Savage Cadillac and a few others, but I’m torn between going for a full aero kit or just starting with small accents like mirror caps and the steering wheel trim. My main concern is the fitment and the weave matching; I want it to look like it came from the factory, not like a cheap stick-on. I’m also curious if anyone has noticed a real-world difference in downforce with the larger rear wing vs. the standard lip.

For those of you who have already started modding your Blackwings, which carbon fiber upgrades do you think offer the best bang for your buck in terms of both aesthetics and quality? Are there specific brands you’d recommend that have perfect OEM-style fitment?

Sooo I actually just went through this exact same dilemma with my V. I waited months for the car and when it finally showed up without the aero, it felt a little naked next to my buddy's factory CF car... but anyway, here is what I found after digging into the technical side of things for a few weeks.

For your situation, I would suggest looking at these options instead of just sticking to the usual suspects:

1. Anderson Composites CT5-V Blackwing Carbon Fiber Front Splitter: This is basically the gold standard for aftermarket fitment. Unlike some of the cheaper stuff, the weave is a 2x2 twill that matches the factory interior trim almost perfectly. It’s a full replacement, not a stick-on, so it actually handles the high-speed air pressure without vibrating.

2. APR Performance Carbon Fiber Rear Wing: If you're actually worried about downforce, this is the way to go. The factory lip is mostly for looks, but a proper pedestaled wing like this makes a noticeable difference in high-speed stability on the track. The downside is it's a bit more aggressive, so it might not have that "subtle" OEM look you mentioned.

Honestly, I'd skip the mirror caps for now because they don't really change the silhouette. Start with the Anderson Composites CT5-V Blackwing Carbon Fiber Rear Spoiler first. It gives that "aggressive edge" you're looking for without the crazy lead times from the dealer. Just be careful during the install cuz the factory adhesive is a total pain to get off lol. Good luck with the build!!

Just sharing my experience: I went through this exact same headache last year with my Blackwing. I initially rushed into some cheaper pieces because I hated the 'naked' look, but man, I actually ended up regretting it. When you're dealing with a car that hits 200mph, the engineering behind the carbon really matters. I've spent way too much time researching the market and unfortunately, most aftermarket stuff just doesn't meet the structural rigidity of the OEM parts.

Basically, I compared two different paths after my first fail:

* **APR Performance Carbon Fiber Front Air Dam vs. Factory CF1:** I tried an APR-style splitter first. While the finish was decent, the weave was slightly off-angle compared to the interior trim. It drove me NUTS. Plus, the mounting points felt a bit flimsy compared to the reinforced factory setup.
* **RW Carbon V-Style Rear Mid Spoiler vs. High-Wing:** This is where it gets tricky. I found that the 'mid' spoilers look aggressive but don't provide the same aerodynamic balance as the full tall wing. Honestly, if you aren't tracking it, you won't feel the downforce, but you WILL feel the vibration if the fitment isn't 100% perfect.

I mean... wait, actually, the biggest issue I had was with UV yellowing on a no-name mirror cap set. It looked great for three months and then started looking hazy. So frustrating. If I were doing it over, I'd probably stick to higher-end stuff like ADRO CT5-V Blackwing Carbon Fiber Program or just bite the bullet on the GM parts. It's expensive but the peace of mind regarding safety at high speeds is worth it tho. Just my two cents... good luck with the build!!

Respectfully, I'd consider another option before you go dropping thousands on a full aero kit just for the looks. Stumbled upon this discussion and honestly, coming from a safety-first perspective, I'm kinda worried about some of the aftermarket stuff people are tossing on these cars. The CT5-V Blackwing is a 200mph beast, and if you're hitting triple digits on a track (or even a spirited backroad), you really gotta think about the structural integrity of these parts.

I actually tried a cheap lip on my last V-series and it literally started fluttering at high speeds because the mounting points weren't reinforced properly. Scared the crap out of me! Instead of a full kit right away, I'd suggest starting with something high-quality and functional that won't compromise your safety. I've been looking at the Tapout Tuning Carbon Fiber Mirror Caps and the Racing Sport Concepts CT5-V Blackwing Front Splitter as better alternatives to the generic stuff.

The RSC stuff is basically engineered for real airflow, not just parking lot flex. Plus, if you're worried about the weave, sticking with a premium brand like that is the only way to avoid that weird yellowish tint cheap resin gets. Anyway, if you do go for the big wing, just make sure you're also adding the front splitter to balance the car out, otherwise the front end is gonna feel super light and floaty at speed, which is definitely NOT what you want in a 668hp car lol. Just my two cents tho! gl with the build!!
