Will this diffuser scrape on driveways or steep inclines?

Diffuser clearance depends on your vehicle's ride height and suspension setup. Measure the gap between your current rear bumper and ground on a driveway approach. The circuit design extends beyond the OEM bumper line—verify ground clearance with your specific suspension before installation.

Is this functional downforce or purely cosmetic?

Circuit styling means genuine aerodynamic intent. The fin geometry is designed to increase rear downforce during high-speed driving. You'll feel the effect most at track speeds; street driving will show stability benefits in cornering and during hard braking.

What finish preparation does carbon fiber need?

Real carbon fiber is durable but benefits from UV protection. Most owners apply a clear coat over the weave to preserve color and guard against oxidation. Sand and prep the surface before applying your chosen finish to ensure proper adhesion.
