ACS Composite Rear Window Spoiler - C8 Corvette Stingray
A C8 Corvette Stingray coupe takes one of two parts and the build year decides which: 50-4-150 through 2024, and 50-4-151 from 2025, cut for the glass GM revised that year. The ACS Composite Rear Window Spoiler is the same molded PC composite lip in both, capping the upper edge of the hatch glass where the factory leaves a cut line.
The Stingray has the longest run of any C8, which is why the split matters more here than anywhere else in the range. A 2021 car and a 2026 car look identical from ten feet and take different parts. Both have the same problem at the top of the rear glass: a bare factory edge, and on a tinted hatch a trimmed film line that never quite disappears. This c8 rear window spoiler closes that edge with a molded lip in Carbon Flash Metallic Black, the finish already on the window bezels either side of it. The phrase corvette c8 spoiler almost always means a wing. This one is not that, and it changes a line rather than the airflow.
