Will this wing interfere with my trunk lid or rear hatch?

The J Spec profile is designed with typical rear deck clearance in mind. Before finalizing mounting location, open your trunk or hatch fully and visually confirm the wing's position does not contact the lid edge. Most builds clear without issue, but your vehicle's specific condition should always be verified.

What mounting hole pattern does this use?

This wing is engineered to use factory roof attachment points. Measure the distance between your vehicle's existing roof holes and confirm alignment before drilling any new holes. If your vehicle's mounting surface differs from stock, minor hole relocation may be needed.

Will this wing stay stable at highway speeds?

FRP wings are rigid when properly fastened and carry minimal weight, so they respond well to speed. The key is secure mounting — use fasteners rated for your vehicle's roof load specs and torque them evenly. Reference your vehicle's service manual for proper fastener torque values to ensure a solid installation.
