Might end up making you slower but for a rwd car increase grip. If you are wanting downforce all around you will want a full flat under tray with a splitter that promotes flow under the car. Air flow above the car typically produces lift unless directed otherwise **Q: Cuantas piezas son?** A: 10 **Q: How do I uninstall?! Without leaving marks that is.** A: With rubbing alcohol **Q: How did you guys manage to get it to stick? I only have 1 sticky side on mine...** A: I wouldn’t put it on. After 2 months they started coming off. The adhesive is SO hard to get off ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice product *by A***R on 28 September 2024* Easy to install,looks good&nice quality ### ⭐⭐⭐⭐⭐ Good *by S***. on 4 January 2024* The RULLINE 10pcs/Set Diffuser Shark Fin Kit is a game-changer when it comes to enhancing the aerodynamics and style of your vehicle.
