Will this diffuser scrape on speed bumps or driveway approaches?

The VR-S diffuser sits just below the bumper line and follows OEM rear overhang geometry. Verify your vehicle's current ground clearance and check the diffuser profile against your local driveway angles before installation. Most owners report zero issues on typical street and highway driving.

Does this provide functional downforce or is it purely cosmetic?

This is a styling piece that complements the VR-S aesthetic. It does not generate aerodynamic downforce. The design channels air flow slightly, but performance gains are negligible—choose this diffuser for the look, not for track performance.

What finish prep should I apply before installation?

Carbon fiber arrives with a clear protective layer. Sand lightly with fine grit if you plan to polish or apply additional clear coat for UV protection. If you prefer to install as-is, the factory finish will hold, though a fresh clear coat extends gloss and color retention significantly.
