ACS Composite Rear Window Spoiler - C8 Corvette Z06

Two part numbers cover the C8 Corvette Z06 coupe and the model year decides which one: 50-4-150 for the 2023 and 2024 rear glass, 50-4-151 for the glass GM revised in 2025. The ACS Composite Rear Window Spoiler is the same piece either way, a molded PC composite lip running the width of the upper hatch edge. Pick the year and the rest of the fitment is identical.

On a Z06 the rear glass is the part of the car people look through. The flat-plane V8 sits under it and the hatch is lit like a display case, which is exactly why the raw factory edge above it reads as unfinished, and why a tint line trimmed a fraction short is impossible to unsee. This c8 rear window spoiler closes that edge with a clean line in Carbon Flash Metallic Black, the finish GM uses on the surrounding window bezels.

Product Details

  • Part numbers: 2023-2024 [50-4-150]CFZ, 2025 and later [50-4-151]CFZ
  • 2023 to 2024 Z06: part 50-4-150
  • 2025 and later Z06: part 50-4-151, cut for the revised GM rear glass
  • Material: PC composite, molded by resin transfer molding
  • Finish: Carbon Flash Metallic Black, the only finish we carry
  • Fixing: High strength 3M tape, applied to the glass edge
  • Drilling: None
  • Install time: Around thirty minutes
  • Body style: Coupe
  • Built: North America

Benefits

  • Finishes the raw upper edge of the rear glass with a molded line instead of a cut one
  • Covers a tint edge that was trimmed short, which is the single most common reason owners buy it
  • Carbon Flash Metallic Black meets the factory window bezels, so it reads as part of the car
  • A corvette c8 spoiler that changes the glass line rather than the aero, so nothing about the way the car drives changes
  • PC composite holds its shape and finish through heat coming off the engine bay below

What to Expect

  • Clean the glass edge, dry fit the spoiler, then peel and set it. No drilling and no fasteners
  • Work in the shade. Tape bonds better on glass that is not baking
  • The line it makes is subtle from ten feet and obvious once you know it is there
