Will this wing stay stable at highway speeds?

Yes. The Prisma profile is engineered for aerodynamic balance across the rev range. Before installation, ensure all mounting points are torqued to factory specification per your vehicle's service manual.

What mounting hole pattern does this use?

The wing is designed for OEM mounting locations on your vehicle. Verify your trunk lid hole alignment before final installation — no drilling should be required if you're using factory attachment points.

Will the wing interfere with trunk operation?

The Prisma design minimizes interference with trunk clearance. Confirm fitment with your specific setup before mounting. If you're adding additional accessories or running a roof rack, measure your total load height to ensure no contact.
