Will this wing stay stable at highway speed?

Yes. The Rainer profile is engineered for deck mounting and the hand-laid carbon fiber construction provides the rigidity needed for sustained speed. Confirm your fastening hardware torque values against your vehicle's service manual before final installation.

What mounting holes does this use?

This wing uses the factory rear glass and deck mounting locations. Before installation, verify your vehicle's OEM hole pattern matches the wing's mounting footprint to ensure a clean fit without additional drilling.

Does carbon fiber need special prep before paint or clear coat?

Sand and prep the surface to remove any release agent residue before applying your chosen finish. A UV-protective clear coat is recommended to preserve the carbon weave and protect against environmental exposure over time.
