ACS Composite Rear Window Spoiler - C8 Corvette E-Ray

The C8 Corvette E-Ray straddles a change GM made partway through its run. A 2024 car takes 50-4-150. A 2025 or 2026 car takes 50-4-151, cut for the revised rear glass. Either way the ACS Composite Rear Window Spoiler is a molded PC composite lip that closes the bare upper edge of the hatch, and nothing else about the two parts differs.

The E-Ray is the C8 that gets driven when the weather turns. All-wheel drive and all-season tires mean winter miles, salt film and a rear hatch that is washed far more often than a summer car's. The upper edge of the glass is where that film collects and where a tint line trimmed a fraction short starts to lift. This c8 rear window spoiler covers the edge with a molded lip in Carbon Flash Metallic Black, so there is a defined line to wash up to instead of a raw one.

Product Details

Benefits

  • Gives the rear glass a finished upper edge instead of the bare cut line the car leaves the factory with
  • Hides a tint edge, which matters more on a car that sees a wash bay every other week
  • Carbon Flash Metallic Black matches the factory window bezels either side of it
  • A c8 corvette rear spoiler that touches the glass line and not the aero, so nothing changes at speed
  • PC composite does not chalk or go gray the way painted ABS trim can after a few winters

What to Expect

  • Clean the glass edge, dry fit the piece, then peel and set it. Nothing is drilled and nothing is removed
  • Do it above sixty degrees if you can. Adhesive tape and cold glass are a poor combination
  • Leave the car overnight before the first wash so the tape reaches full strength
