Will this wing maintain stability at highway speeds?

Yes. The Z28 profile is engineered to generate downforce and improve rear-end grip during sustained high-speed driving. The FRP construction keeps weight minimal while the panel design handles the aerodynamic loads.

What mounting holes does this use?

The wing is designed around OEM trunk lid mounting points. Verify your trunk's hole pattern matches the panel before final installation—reference your vehicle's service manual or test-fit with clamps first.

Does the trunk lid open freely with this wing installed?

In most setups, yes—the Z28 profile sits at an angle that clears the trunk mechanism. However, some aftermarket latches or reinforced hinges may require minor fitment adjustments. Test the lid's full travel before finalizing bolts.
