Frequently Asked Questions
Does installation require drilling into the deck lid?
No. This spoiler uses the factory mounting points already on the deck lid. No new holes are required, the install is non-destructive and uses the OEM bolt pattern.
Will this affect the power trunk or factory backup camera?
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.
Can this spoiler be painted to match my vehicle?
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.
Does this spoiler pair with the Anderson Composites trunk lid?
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.
Is this spoiler street legal in all 50 states?
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.
How long does installation take?
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.
What weight savings can I expect over the factory spoiler?
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.
Does this product come with a warranty?
Yes. Anderson Composites provides a limited manufacturer warranty on materials and workmanship. Coverage does not extend to impact damage, improper installation, or handling damage. Contact Anderson Composites for current terms.

- Clean all mounting surfaces to remove adhesive residue and debris
- Test-fit the AC-RS15FDMU350-OE to confirm alignment and gap before final fastening
- Set the spoiler onto the mounting studs and thread the nuts to hand-tight
- Adjust for uniform gap around the perimeter, then torque to factory specification
