Will this diffuser scrape on driveways or steep approach angles?

The diffuser follows M Performance OEM proportions and mounts at factory attachment heights. Ground clearance depends on your suspension setup and ride height. Measure your current ride height and compare against the OEM diffuser dimensions before installing if you frequently navigate steep angles.

Does this add downforce or is it purely cosmetic?

This is a styling piece that replicates M Performance visual proportions. Real aerodynamic benefit requires proper underbody sealing and air path engineering beyond the diffuser alone. Install it for the aesthetic—don't rely on it as a functional aero upgrade by itself.

What prep work is needed before painting?

Sand and prep the surface according to your chosen paint system's requirements. Your painter will guide grit selection and any primer or sealer steps based on the topcoat you select. Do not skip surface prep—it directly affects paint adhesion and finish quality.
