Will this scrape on driveway inclines or speed bumps?

The AMK diffuser sits at the factory bumper line—same as the OEM rear panel. If your vehicle clears factory dips and parking lot transitions, this diffuser will too. Check your current ride height and any suspension modifications that may lower the rear end.

Can I use this diffuser as functional downforce or is it cosmetic?

This is a styling diffuser designed for visual appeal. While the AMK profile echoes performance aesthetics, it does not generate aerodynamic downforce on its own. It enhances the rear-end look and pairs well with other body modifications.

Does the diffuser come with mounting hardware?

The diffuser assembly ships as pictured above. Verify your vehicle's OEM rear bumper fastener configuration before installation, and reference your service manual for the correct hardware torque specifications.
