Will this spoiler interfere with the trunk lid when opening and closing?

No. The spoiler profile and mounting location are designed to clear the trunk lid swing arc. Verify clearance by checking the factory mounting hole pattern on your trunk before final installation to ensure alignment with your vehicle's specific hole locations.

What mounting holes does this spoiler use?

This spoiler is engineered for factory trunk lid attachment points. Confirm the hole pattern on your trunk lid matches the spoiler's pre-drilled locations before securing fasteners. Reference your vehicle's service manual or OEM trunk assembly diagram if you need to verify exact hole spacing.

How stable is this wing at highway speeds?

FRP spoilers are rigid and balanced for highway use when properly mounted. Secure all fasteners per your vehicle's service manual torque specifications to ensure stability. Even weight distribution across all mounting points is critical — do not skip any fastener holes.
