Key Features

Perfect Fitment for 2020-Present Cadillac CT5 Models (Without Carbon Fiber Package)
Specifically engineered for CT5 Sport, CT5-V, and CT5-V Blackwing models without the OEM carbon package. The design lines and mounting points match factory specifications for precise alignment. Does not fit base CT5 or CT5-V Blackwing models equipped with the OEM Carbon Fiber Package.

3K Twill Weave Real Carbon Fiber Construction
Manufactured using genuine 3K twill weave carbon fiber, offering superior strength, low weight, and a deep, race-inspired aesthetic. Each piece is carefully layered and resin-infused for optimal rigidity and durability under daily and performance driving conditions.

High-Gloss UV-Resistant Finish
Protected with a high-gloss clear coat that resists UV rays, oxidation, and weathering. The finish maintains a rich carbon depth and mirror-like shine over time — ideal for show cars and enthusiasts who demand perfection.

Carbon Package Style Design
Modeled after Cadillac’s OEM Carbon Package aerodynamic components. This style adds a factory-correct visual upgrade that seamlessly blends with other carbon fiber accents such as front splitters, rear diffusers, and mirror caps.

Aerodynamic Enhancement
The extended side skirt profile channels airflow along the lower body to reduce turbulence and drag, providing subtle improvements in stability and overall aerodynamic balance at highway or track speeds.

Lightweight and Durable
Despite its aggressive styling, the dry carbon construction remains exceptionally lightweight — reducing unsprung mass and maintaining the CT5’s refined handling characteristics.

Direct Bolt-On Fitment
Designed for a straightforward bolt-on upgrade using factory-compatible mounting points. Includes a hardware set for installation and features pre-marked drill holes for precise alignment.

Installation

1. Lift the vehicle using a jack and ensure stable support before installation.

2. Clean the lower rocker panel surfaces thoroughly to remove dust, oil, or debris.

3. Align each side skirt to confirm positioning along the factory body line.

4. Drill into the pre-marked holes on the skirt surface as required.

5. Secure the side skirts using the provided hardware kit.

6. Verify alignment on both sides before fully tightening.

Professional installation is highly recommended.
Minor drilling may be required for the most secure and flush fitment.

About Dry Carbon Fiber

Dry Carbon Fiber vs Wet Carbon Fiber — What’s the Difference?

Not all carbon fiber parts are made the same. The biggest distinction comes down to how the carbon is processed — commonly known as dry carbon and wet carbon. Both use genuine carbon fiber weave, but the production method, finish, and performance are completely different.

Manufacturing Process

Dry carbon fiber parts are produced using a pre-preg (pre-impregnated) carbon cloth, where the exact amount of resin is pre-applied by the manufacturer. These sheets are then vacuum-sealed and cured under high pressure and temperature in an autoclave, removing excess air and resin.
The result is a light, extremely strong, and precisely formed component — the same process used in motorsport and aerospace applications.

Wet carbon fiber, on the other hand, uses a hand-lay or wet-lay method. The carbon cloth is laid into a mold and liquid resin is manually brushed or poured over it before curing. Because it’s not vacuum-bagged or autoclave-cured, there’s usually more trapped resin and air pockets, leading to a heavier part and a less uniform finish.

Weight & Strength

Dry carbon fiber is roughly 30–50% lighter than wet carbon. This is due to the controlled resin ratio — just enough to bind the fibers without unnecessary weight.
By comparison, wet carbon or carbon-over-fiberglass parts can be up to 70% heavier, since excess resin and fiberglass layers add mass without increasing stiffness.
For reference:

• Carbon Fiber Density: ~1.55 g/cm³
• Fiberglass Density: ~2.6 g/cm³

Dry carbon also offers a much higher modulus of elasticity (~125 GPa), giving it outstanding rigidity under stress — ideal for aerodynamic and high-load components.

Visual & Structural Differences

• Backside: A true dry carbon piece will look identical front and back — you can see the same woven pattern throughout.
  Wet carbon or fiberglass-backed parts often have a dull, uneven underside with visible fiberglass texture or color variation.
• Edges: Solid dry carbon has clean, uniform black edges.
  Wet carbon or overlay parts may show a white or grey line along the edge, revealing the fiberglass underneath — sometimes hidden with black paint trim.
• Finish: Dry carbon typically has a consistent matte or satin finish, while wet carbon can appear glossy but uneven due to hand-applied resin.
