Will these interfere with the trunk seal or hatch movement?

The two-piece design sits cleanly at the rear and does not extend into the trunk lid or hatch path. Verify ground clearance and rear bumper fitment against your vehicle's current setup before final installation.

Can I install these without drilling new holes?

These diffusers are engineered to use factory mounting points. Compare your vehicle's OEM rear panel hole locations to the diffuser mounting pattern before committing to adhesive or fastener choice.

What prep work is needed before painting?

Sand and prep the surface with standard automotive-grade abrasive media before applying basecoat or clear. Follow your paint system's recommended surface prep steps for best adhesion and finish longevity.
