Hello Everyone, For Toyota Prius ZVW30 (2013 My Coordination Version), I need to fix a Hexagon shape spoiler. I assume it has to be fixed on low profile factory fitted default spoiler. I hope users here have fixed same already and need their reviews: (Picture attached) 1. Have you felt new spoiler has affected aerodynamics in bad way, after fixing it? 2. Felt any driving/balancing/shaking issue during the ride? 3. Occured any mileage issues? 4. Toyota not recommends to fix this? Thanks.
