Will this diffuser scrape on steep driveways or inclines?

The DLR design sits close to the factory bumper profile, so clearance mirrors your stock rear bumper. Check your driveway angle before installation—if you ground the OEM bumper, this diffuser will have similar contact points.

Is this functional or purely cosmetic?

This is a styling piece designed to enhance the rear aesthetic in the DLR proportion. It does not generate downforce or alter airflow characteristics—focus is on visual presence.

Does carbon fiber require special maintenance?

Apply a UV-protective clear coat before installation to preserve the weave finish and prevent oxidation. Once coated, treat it like any painted panel—regular wash and occasional wax will keep it looking fresh.
