Extreme Online Store's complete 2020-Up Cadillac CT4, CT4-V and CT4-V Blackwing catalog — carbon fiber exterior trim, rear spoilers and exhaust systems, designed and test-fitted on the CT4. Engines across the range: the 2.0L and 2.7L turbo fours and the twin-turbo 3.6L V6 in the CT4-V Blackwing.
CT4 and CT4-V share the standard body; the Blackwing adds its own front fascia, splitter, rear diffuser and spoiler. The 2025 refresh changed the front end, so front pieces are sold as 2020-24 or 2025-Up. Use the Category row on the left to go straight to a part type; each listing states the exact trims and model years it fits.
Materials run carbon fiber, dry carbon fiber, ABS plastic and T304 stainless for exhaust. Every carbon fiber part is UV clear-coated for outdoor use; ABS and polypropylene parts ship primed or finished as listed.
Frequently asked
Do you ship free? Yes — free shipping to the 48 contiguous states on every CT4 part.
Are these direct fit? Every part here is designed on the actual car and confirmed for fitment. Installation notes and hardware requirements are on each product page.
Carbon fiber or ABS? Carbon fiber is lighter and stiffer with a visible weave under clear coat. ABS is more impact-tolerant and usually ships primed or gloss black — a good choice for splitters that may see driveway contact.
