Will this wing stay stable at highway speeds?

Yes. Real carbon fiber and hand-laid construction provide the rigidity needed for highway use. Ensure mounting points are torqued to spec per your vehicle's service manual and verify proper fitment before driving.

Does the trunk lid need modification for clearance?

Check your specific mounting location before installation. The MSR design is compact, but trunk lid interference depends on your exact spoiler positioning. Measure the wing height relative to your trunk opening during test fit to confirm clearance.

What prep work is needed before finishing?

Sand and prep the surface thoroughly to remove any manufacturing residue or dust. Once clean and dry, apply UV-protective clear coat to preserve the weave pattern, or paint to match your build. Proper prep ensures a clean, long-lasting finish.
