Will this diffuser scrape on driveways or steep inclines?

Diffusers sit close to the rear bumper plane and add minimal extension. Verify fitment by measuring your current rear bumper clearance before installation — steep approach angles depend on your vehicle's stance and suspension setup.

Does this diffuser provide functional downforce or is it purely cosmetic?

This is a styling piece that complements your rear bumper's appearance. While the Emery design follows aerodynamic lines, real downforce requires testing at track speeds; treat this as a visual upgrade that frames your rear end with an aggressive profile.

What mounting hardware is required?

Verify the OEM mounting points on your rear bumper before ordering. Your diffuser will integrate using factory attachment locations; reference your vehicle's service manual or bump test the fitment against the bumper flange to confirm bolt patterns.
