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

No. The K Spec profile is designed with trunk clearance in mind. Verify fitment by measuring from your trunk edge to the rear bumper on your vehicle before final installation — this ensures adequate hood swing clearance with your specific trim configuration.

What mounting hole pattern should I use on the trunk lid?

The wing is engineered to use the stock trunk lid fastener locations. Reference your vehicle's service manual to locate the OEM bolt holes and their spacing, then align the wing accordingly. Most installs require four mounting points for stability.

How stable is this wing at highway speeds?

FRP wings are rigid and hold their shape well at speed. Stability depends entirely on proper fastening — ensure all mounting bolts are torqued securely and evenly. Refer to your vehicle's service manual for recommended fastener torque values to achieve optimal vibration-free performance.
