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 ### ⭐⭐⭐⭐⭐ Review *by S***. on January 4, 2024* ### ⭐⭐⭐⭐⭐ Review *by E***G on September 25, 2025* ### ⭐⭐⭐⭐⭐ Review *by C***G on July 26, 2021* ## Frequently Bought Together - RULLINE 10pcs/Set Diffuser Shark Fin Kit Compatible with Spoiler Roof Wing Air Vortex Generator Black - 2PCS Universal Hood Air Vents for Car Hood Scoop, Bonnet Vent Hood Air Intake Trim Cover (Black) - GKmow Pack-6 Car Spoiler Canards Kit, Universal Auto Front Bumper Lip Splitter, Body Anti-Collision Diffuser, Exterior Soft Rubber Decorative Stickers (Glossy Black) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/38432632-rulline-10pcs-set-diffuser-shark-fin-kit-compatible-with-spoiler](https://www.desertcart.at/products/38432632-rulline-10pcs-set-diffuser-shark-fin-kit-compatible-with-spoiler) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-05-06*
