FINAL SALE: SOLD AS-IS. NO RETURNS, NO REFUNDS, NO EXCHANGES.
Product Overview
Outlet / Defective Return Item: This GM Factory Extended Replacement Style Dry Carbon Fiber Rear Trunk Lid Upper Wing Spoiler for the 2019 Chevrolet Corvette C7 ZR1 is being sold as-is as a defective return / outlet item from Extreme Online Store. It may show cosmetic defects, blemishes, scratches, scuffs, clear coat imperfections, installation marks, signs of prior handling, or other condition issues. Please review the actual product photos carefully before purchasing.
This spoiler is designed as a direct replacement for the OEM ZR1 rear spoiler, with an extended aerodynamic surface area intended to increase rear downforce and maintain the OEM body lines of the C7 ZR1. Constructed from 3K Twill Weave Dry Pre-Preg Carbon Fiber, this outlet item retains the original product design and material specification, but is not being sold as a new-condition item.
The dry pre-preg process is used to create a stronger, more consistent carbon fiber structure compared to wet lay-up methods, with a smoother weave pattern, cleaner finish, and reduced weight. The high-gloss clear-coated surface is designed to enhance the carbon weave texture and provide UV protection; however, this specific defective return item may have visible finish or cosmetic imperfections.
Engineered using precision CAD modeling, this spoiler is molded for an OEM-style fit and installs using the factory mounting area. No drilling or modification is required — re-use the OEM hardware for a secure bolt-on installation. Because this is a final sale outlet / defective return item, buyers should inspect all photos and understand that condition may vary from a standard new product listing.

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.
