Will this diffuser scrape on inclines or driveways?

The UTech diffuser drops lower than OEM, so confirm ground clearance on your typical driving surfaces before installation. Measure the distance from the rear bumper bottom to the pavement on your driveway's steepest approach angle, then account for the additional depth this diffuser adds. If you have low approach angles, test fit or use a speed bump to verify clearance.

Is this functional downforce or purely cosmetic styling?

UTech rear diffusers are primarily aggressive styling pieces—they enhance the visual profile of the rear undertray. While the deeper blade design follows aerodynamic principles, real downforce benefit is minimal at street speeds. This is built for looks first, not track performance.

Does the clear coat need maintenance to stay glossy?

The UV-protective clear coat will maintain its finish with basic care. Wash regularly and apply a UV-rated automotive sealant or wax every 3–4 months to preserve the gloss and protect the carbon fiber from oxidation. Avoid harsh cleaners or abrasive pads that can compromise the clear coat.
