What mounting hole pattern does this use?

This wing is designed for factory roof mounting points on the vehicle. Verify your roof's existing hole locations and spacing before drilling or fastening. If drilling new holes, measure twice and reference the wing's base to ensure proper alignment and weight distribution.

Will this interfere with a rear trunk lid or hatch when it's open?

The D1 profile is positioned to sit above the rear window line and does not extend into the trunk lid opening. Clear the mounting area of any obstructions and test fitment before final fastening to confirm compatibility with your specific vehicle configuration.

Does this wing stay stable at highway speed?

Once properly secured with the correct fastener torque to factory specifications, the rigid FRP construction and mounting design maintain their integrity at speed. Ensure all mounting bolts are fully tightened to your vehicle's service manual torque values and check them periodically after installation.
