Will this scrape on steep driveways or parking lot inclines?

The Exe profile sits closer to the bumper line than most aftermarket diffusers, minimizing overhang. Verify ground clearance on your specific vehicle before final install — approach angles vary by suspension setup and ride height.

Does this diffuser provide actual aerodynamic benefit or is it purely visual?

The Exe design channels air away from the rear axle and deck lid, which improves flow stability at speed. It's functional geometry, not just styling — you'll feel the difference on highway runs and tight cornering.

What finish should I apply — do I need to sand and prime before clear coat?

Sand and prep the surface before applying your chosen finish. Carbon fiber accepts clear coat directly, but surface prep ensures adhesion and durability. A UV-protective clear is recommended to maintain the weave visibility over time.
