Race-Inspired Carbon Fiber Rear Spoiler Purpose-Built for the 2020-2023 Ford Mustang GT500

No. The spoiler is designed around the OEM trunk lid geometry and does not interfere with the factory latch or release. On vehicles with a camera integrated into the spoiler mount area, verify the camera location relative to the new spoiler before ordering.

Yes. The gel coat surface accepts standard automotive paint. Sand lightly, prime with a flexible composite primer, then apply basecoat and 2K clear coat for a color-matched result.

Yes. Anderson Composites designs their spoilers to complement their trunk lids with consistent weave patterns and finish levels. Running both creates a seamless coordinated look across the entire rear of the vehicle.

Yes. This is a direct OEM-style replacement spoiler that does not alter any safety systems or exceed factory spoiler dimensions. It is fully street legal nationwide. California residents should note the Prop 65 disclosure at the bottom of this page.

Most installers complete the swap in one to two hours. The process involves accessing the mounting nuts from inside the trunk, removing the OEM spoiler, cleaning the deck lid surface, and securing the new spoiler using the factory mounting pattern.

Anderson Composites carbon fiber construction achieves up to 50% weight savings over the factory unit. High-mounted rear weight affects the vehicle's pitch dynamics, so even a modest reduction at this location has a measurable effect on handling balance.
