Will this wing stay stable at highway speeds?

Yes. The single-piece FRP construction is engineered for rigidity under load. Ensure mounting points are torqued securely per your vehicle's service manual and verify the wing sits flush against the trunk surface before final tightening.

Does this wing interfere with the trunk lid?

The Plasma design mounts at the trunk's top edge with minimal extension. Before installation, open your trunk fully and visually confirm the wing clearance. If you've added aftermarket trim or spoilers, verify their overlap won't restrict lid movement.

What's the mounting hole pattern, and will I need to drill new holes?

Reference your vehicle's OEM trunk-mounted spoiler attachment points — this wing is designed to use factory holes where they exist. Measure your trunk's hole spacing and compare it to the wing's fastener pattern before purchase to confirm fit with existing hardware locations.
