Will this diffuser scrape on driveway approaches or ramps?

The Speed Tune style sits close to the factory bumper line with minimal extension. Check your typical entry angles and verify clearance before final installation—most standard driveways won't cause contact, but steep inclines may require cautious approach.

Does this diffuser add downforce or is it cosmetic?

This is a styling piece designed to complement the rear bumper aesthetic. It's not engineered as a functional aerodynamic component—focus on finish quality and fit rather than performance gains.

What prep work is needed before painting?

Sand and prep the surface to your chosen finish standard. Standard automotive body work applies—no special FRP-specific process required beyond normal surface preparation before paint or coating application.
