I installed this myself without any help. If you don't have someone to help balancing it, you can use floor jack by laying the diffuser on top. After installing the diffuser, you may or may not like it from the high sideview angle. At least I thought it was little odd and blocky. For a few days, that weird disconnected look bugged the heck out of me and it was sticking out like a sore thumb. It desperately needed a smooth finishing end. The only solution was the side spats attachment. I studied the photos from the review with attachment and thought to myself it may actually work. Those photos weren't great shots but they gave me general ideas of how it's gonna look. After installing rear spats, it looked 10 times better. They were meant to be together from the beginning like bread and butter. So I highly recommend you to get both. Review: Way Less Butterknife, Way Mo’ AK-47! - I finally got this product Nov. 6 after ordering it in July. It arrived by USPS in very good condition and was packed well in expansion foam. The factory must have shipped it as soon as it was made ‘cause it smelled like fresh carbon fiber resin. The diffuser was easy to mount, although I added additional 3M mounding tape. It also came with 10 plastic screws, but there are only 3 screw holes on the bottom. This diffuser does make the P3D look more aggressive, just hoping it will last through the winter. The diffuser is very light and appears to be made of real carbon fiber. So if you want a meaner looking M3 get one. You’ll make the the ICE “Toonies” go Looney, ‘cause all they can make is Noise Not Pure Acceleration like a Tesla, and the diffuser visually backs it up. ## Features - ⭐【Custom Fitment】:This Rear Diffuser Fits for Tesla Model 3 Sedan 2017 2018 2019 2020 2021 2022 2023 - ⭐【High Quality Material & Durable】:Carbon Fiber aerodynamics parts are using extremely strong, air craft high-grade carbon fiber material which are lighter in weight and high tensile strength ,this ensures long lasting service life you expect.Ultra high-gloss clear gel-coated finish & UV protected, this ensures long lasting service life you expect. - ⭐【Easy Installation】:The rear lip is installed with tape and tapping screw.Highly recommend professional installation.(This rear diffuser is a part of the kit, you can take the whole kit in our store, get the better appearance and save more.)Our carbon fiber parts are lightweight in comparison with other materials, giving you a weight reduction gain on your build.alance can enhance the car's sporty performance ,makes the car more dynamic. - ⭐【Beautiful Appearance】:This Rear Lower Lip Valance can enhance the car's sporty performance ,makes the car more dynamic. - ⭐【Superior service】: If there is anything we can do for you, please feel free to contact us. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07ZD5M13Z | | Auto Part Position | Rear | | Best Sellers Rank | #3,226,766 in Automotive ( See Top 100 in Automotive ) #10,382 in Spoilers #384,756 in Automotive Body Parts | | Brand | JC SPORTLINE | | Brand Name | JC SPORTLINE | | Color | Carbon Fiber | | Compatible with Vehicle Type | for Tesla Model 3 2017-2023 | | Customer Reviews | 4.8 out of 5 stars 8 Reviews | | Exterior Finish | 3K weave carbon firber rear lip spoiler for tesla model 3 2016-2023 | | Included Components | / | | Installation Type | Screw-In | | Item Type Name | / | | Manufacturer | JC SPORTLINE | | Manufacturer Part Number | JS-2778 | | Manufacturer Warranty Description | 30 day | | Material | Carbon Fiber | | Material Type | Carbon Fiber | | Vehicle Service Type | for Tesla Model 3 2017-2023 | ## Images ![Real Carbon Fiber Rear Diffuser for Tesla Model 3 2017-2023 Bumper Cover Lower Lip Spoiler Valance Protector Body Kits Factory Outlet - Image 1](https://m.media-amazon.com/images/I/61N-oDe-0vL.jpg) ## Questions & Answers **Q: How to confirm whether this product fits my car or not?** A: PLS contact and send us your car pictures if not sure the fitment, then we will check it. **Q: Is this true carbon fiber or plastic with a carbon fiber cover?** A: The spoiler is made of real carbon fiber (3K) with stylish design **Q: How long it will take to arrive after payment?** A: It will take 3 days ships by Amazon.

May want to use rubber washers or alternate fasteners rather than the included long screws, but they worked for alignment and to get a hole started. Arrived within the estimated window — i.e. took a while since it’s coming from overseas, but packaged well and I’m very satisfied with the splitter. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/214513664-real-carbon-fiber-rear-diffuser-for-tesla-model-3-2017](https://www.desertcart.pl/products/214513664-real-carbon-fiber-rear-diffuser-for-tesla-model-3-2017) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
