Will this wing maintain stability at highway speeds?

Yes. The D1 profile is designed for aerodynamic function, not just appearance. Ensure the mounting surface is clean and fasteners are torqued properly per your vehicle's service manual to maintain secure attachment under all driving conditions.

What mounting hole pattern does this use?

The wing is engineered to use factory-location mounting points on your vehicle. Verify your trunk lid mounting holes align with the wing's attachment points before final assembly. Minor drilling may be required depending on your specific setup — reference your OEM documentation.

Will the wing interfere with my trunk lid opening?

The D1 style is designed with clearance in mind, but trunk lid interference depends on your exact panel condition and modification history. Check clearance with the lid fully open before final fastening. If fitment is tight, the mounting surface or wing height may need minor adjustment.
