Will this interfere with trunk lid operation?

No. Verify clearance by checking your vehicle's OEM trunk lid shape and the spoiler's mounting location on your specific trim level. Factory mounting points are designed to avoid interference when the lid opens fully.

What mounting hole pattern does this use?

The spoiler uses the factory trunk panel hole locations. Before installation, inspect your trunk lid surface to confirm existing holes or mounting points match the wing's base. If your trunk has been repaired or modified, verify hole alignment before final mounting.

How stable is this at highway speeds?

FRP wings are stiffer than unpainted plastic and resist flex under aerodynamic load. Proper mounting torque and secure fastener engagement are critical—refer to your vehicle's service manual for fastener torque specifications. Over-tightening can crack FRP; under-tightening reduces stability.
