Seconding the recommendation above. Honestly, Savage is the go-to for most, but over the years I've learned you can actually get that same dry carbon look for less if you're patient. I'd definitely look into Cuztom Tuning Real Carbon Fiber Mirror Cover Caps for Cadillac CT4. They're basically 3K twill weave and fit pretty well for about $100. Pro tip: apply some Meguiar's G190526 Hybrid Ceramic Wax every few months to stop that yellowing you're worried about. Gl!

I totally agree with the advice to avoid those cheap stick-ons, they basically look like a DIY project gone wrong. I’ve been doing some heavy market research because I’m super CAUTIOUS about putting stuff on my car that might fly off on the highway or yellow in two months. Heres a quick comparison of a few other brands I looked into while scouring the forums: - EOS Extreme Online Store Carbon Fiber Mirror Caps: Theyre basically the middle ground for price and quality. Pros are they use a decent resin and the price is fair, but the CON is fitment can be a bit tight. I've heard some people have to trim the clips slightly to get that perfect flush look, which makes me a bit nervous tbh.
- Next-Gen Speed Carbon Fiber Mirror Replacements: These seem like a safer bet for longevity. Pros: The weave is SO consistent and they specialize specifically in the CT4/CT5 platform. Cons: Theyre definitely pricier than the eBay stuff and sometimes there’s a waitlist if theyre out of stock. Im still a bit unsure about the long-term UV finish on these aftermarket parts compared to the official GM performance ones, but those two seem to have the best track records for not falling apart. It just feels like a risk either way tho.

> Specifically, I’m curious if anyone has tried the ones from Savage Cadillac or maybe some of the higher-end brands?

I feel u on the cheap plastic stuff—it literally ruins the vibe. For your situation, I've gotta say Savage Cadillac is actually legit!! I swapped my CT4 caps for their full replacement ones and the fitment is basically OEM. No gaps at all. Seriously, the weave is 2x2 and looks amazing in the sun. I mean, I've had mine for a year and zero yellowing so far. Definitely worth the extra cash over eBay junk... gl! 👍

Seconding the recommendation above. Savage is decent, but if you want to save some cash, check out the Jcsportline Carbon Fiber Mirror Covers for Cadillac CT4.

I mean, basically all these "dry carbon" ones use the same 3K twill weave specs. I snagged a set for around $120 on sale and the fitment was surprisingly tight with zero gaps. Just make sure you get the full replacements, not the 3M stick-on ones tho... those look tacky tbh. gl!
