## Questions & Answers

**Q: Will it make my Ford Fusion s go faster????**
A: If it’s a fast back or standard sedan this in addition to a spoiler will improve downforce. 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
