Will this wing stay stable at highway speed?

Yes. The Varix profile is aerodynamically designed for downforce, and FRP construction provides rigidity once fully secured to the factory mounting points. Ensure all fasteners are tightened per your vehicle's service manual for optimal stability.

Does the rear wing interfere with the trunk lid when opening?

The Varix profile is engineered to sit clear of the trunk hinge arc on standard configurations. Before installation, verify trunk clearance with the wing mocked into position — modifications to mounting height or angle may be needed based on your specific trim and aftermarket parts.

What mounting hardware do I need?

The wing uses the factory hole pattern, so you'll need fasteners that match your vehicle's OEM mounting specifications. Reference your service manual for the correct bolt size, washer type, and torque specs to ensure a secure, lasting fit.
