Will this diffuser scrape on steep driveways or inclines?

Diffusers sit closer to the bumper line than extreme body kits, so ground clearance mirrors your stock rear overhang. Check your driveway angle before installation and reference your vehicle's OEM body clearance specs if you're unsure.

Is this functional downforce or purely cosmetic?

This is a styling piece that complements your rear end appearance. Any aerodynamic benefit from a diffuser depends on vehicle speed, angle of attack, and overall body package — not the diffuser alone. Treat it as aesthetic enhancement first.

Does the clear coat need maintenance?

The UV-protective coat is baked on during manufacturing, but regular washing keeps the finish clean and extends its life. Avoid abrasive polishing compounds; use standard automotive soap and microfiber cloths. Clear coat protects the weave from UV, but like any exterior finish, it benefits from occasional maintenance.
