Will this wing interfere with my trunk lid or sunroof operation?

Measure your roof profile and compare to the D1 extension height before finalizing mounting location. Most roofs accommodate this wing without clearance issues, but verification on your specific vehicle ensures you avoid any binding during panel adjustment.

What mounting hole pattern does this use?

Reference your vehicle's OEM roof attachment points to determine fastener count and spacing. Factory roof structure typically provides multiple mounting options; test-fit the wing upside-down on sawhorses before drilling any holes, then mark pilot points for your setup.

How stable is an FRP wing at highway speeds?

FRP is rigid enough for street use when mounted securely to factory roof structure with proper fasteners. Refer to your vehicle's service manual for fastener torque values and recheck after your first 100 miles of driving to ensure all connection points remain tight.
