Will this diffuser scrape on steep driveways or inclines?

The ZL1 profile sits lower than most body kits, so it's more prone to contact on steep approach angles. Check the ground clearance at your driveway entrance before installation. If scraping is a concern, verify the OEM ZL1 diffuser height matches your typical driving conditions — this panel replicates that exact profile.

Does dry carbon need a clear coat, or can I drive it as-is?

Dry carbon is uncoated and will oxidize without protection. A quality UV-protective clear coat preserves the weave pattern and prevents discoloration. You have full control over gloss level — matte, satin, or gloss — depending on your finish choice.

Is this functional downforce or purely cosmetic styling?

This is a style-matched replica of the ZL1 factory diffuser. It follows OEM proportions for visual authenticity. For measurable aerodynamic effect, airflow, chassis setup, and rear suspension geometry all factor into downforce — not the diffuser alone. Install it for the ZL1 look; expect functional benefits aligned with what the factory design provides.
