Will this wing maintain stability at highway speeds?

Yes. The GT350 profile is engineered for both aesthetic impact and aerodynamic function. Ensure all fasteners are torqued per your vehicle's service manual and that the two pieces are aligned flush before final tightening.

What's the correct mounting hole pattern for this wing?

This wing uses your vehicle's factory rear wing mounting locations. Verify hole alignment with your existing bracket points before drilling or fastening. If holes don't line up, adapters or minor drilling may be required — check clearance against your trunk lid and rear panel first.

Will the wing interfere with my trunk lid when opening?

Measure the vertical distance between your trunk lid edge and the mounting surface before installation. The GT350 profile sits higher than OEM spoilers, so confirm clearance on your specific car. Test the lid fully open and closed after securing the first piece.
