Do these need clear coat protection?

Yes. Clear coat seals the carbon weave, protects against UV yellowing, and keeps the finish looking factory-new. Sand the surface lightly and apply your chosen automotive clear over the carbon before installation.

Will the carbon fiber edges crack or splinter?

Real carbon fiber edges are stable when sealed. Once you've cleared the panels, the perimeter is protected. Any raw edges that stay exposed will benefit from a coat of epoxy or edge trim to prevent moisture ingress and maintain appearance long-term.

How do I verify these fit my setup?

Check the factory rocker panel mounting points on your vehicle — they should align with the bolt holes on the carbon panels. If you've modified your body kit or suspension geometry significantly, test-fit before final installation to confirm clearance.
