Will this wing affect trunk lid operation or clearance?

Trunk lid interference depends on mounting location and height. Verify clearance by checking your vehicle's OEM spoiler mounting points and measuring downward from the wing base to the trunk edge before final installation.

What mounting hole pattern does this use?

Reference your vehicle's factory spoiler bracket holes to confirm alignment. Most bolt-on spoilers use existing rear panel threaded inserts. Test-fit the wing in position and mark holes before drilling or tapping any new fastener points.

Is this wing stable at highway speed?

FRP wings are engineered for highway use when properly secured and aligned. Ensure all fasteners are torqued evenly to eliminate vibration. Refer to your vehicle's service manual for correct fastener torque values and use lock washers to prevent loosening over time.
