Will this diffuser scrape on driveways or inclines?

The 3DS design adds minimal extension to the rear bumper profile. Verify ground clearance against your vehicle's ride height and any suspension modifications before installation. Lowered setups may require adjustment to approach angles on steep driveways.

Is this functional downforce or purely cosmetic?

The 3DS diffuser is styled for visual impact. Real aerodynamic benefit depends on vehicle speed, rear wing presence, and overall body kit setup. It complements a complete aero package but works equally well as a standalone cosmetic upgrade.

What finish should I use on raw carbon?

Clear coat is recommended to protect the weave from UV fade and road debris while maintaining visibility of the carbon texture. Sand and prep the surface per your chosen clear coat manufacturer's specs before application.
