## Description

The main benefit of having a rear spoiler on a car is often times to reduce the drag. Less drag can mean a bit of a boost in fuel efficiency. Spoilers also act to reduce lift without adding more weight to the car. This can help keep the car more stable at higher speeds and improve traction without affecting its performance by adding excess weight. Most spoilers on the market requires you to drill holes into your trunk. One little mistake will ruin your vehicle, not to mention it is very time consuming. Our spoilers are designed for easy installation, quick Sunday morning project. The spoiler is attached using automotive grade double sided adhesive tape. To ensure the spoiler stays attached, we recommend the surface of the trunk is cleaned throroughly as it will help the spoiler to remain in place securely. After the spoiler has been installed, please refrain from washing your car for at least 3 days. This will help the glue to set in and cure.Specifications:- Condition: 100% Brand New- Fitment: Compatible with BMW 4 Series Gran Coupe fastback F36 4 Door Model 420i 428i 430i 435i 440i xDrive- Year: 2014-2020- Package includes: 1 rear trunk spoiler, 1 roll of adhesive tape- Finish: Glossy Black- Material: High Impact ABS* Note:- The roof spoiler is painted in glossy black- Installation instruction is NOT included, professional installation is recommended if you are unsure of the installation process.- This is a non-OEM product- Compatible vehicles above for reference only

Review: Excellent product for $125 - This is actually an excellent product with high quality paint finish. Paint finish is car paint quality. Very shiny. It was very well packaged (double insulation wrap plus large cardboard box) and received in sound condition. I was impressed with the quality given its low cost ($125). It is a bargain. The key is to NOT USE the included 3M black colored double sided tape. It will not hold as it is too thin and week. INSTALATION INSTRUCTIONS: 1. CLEAN application surface with undiluted 70% alcohol. Clean and reclean. This removes dirt, wax, and residue. 2. PREP SPOILER. Clean adhesive side with undiluted 70% alcohol. 3. PURCHASE 3M GRAY COLORED double-sided adhesive tape. DO NOT USE the 3M black colored double-sided adhesive tape that is provided. IT WILL NOT HOLD particularly at the slightly curved corners. The spoiler is not contoured to trunk curvature. It is flat and the curvature at the ends will pull and separate almost immediately. It will not stick and at most only hold for a day or two. 4. CUT the 3M gray colored double sided adhesive tape to widths of 1/4 to 1/2 inch in strips 6 to 8 inches long (similar to width of included black colored double-sided adhesive tape). This is the tedious part. Very tedious. Patience required and quality scissors. Attach the strips along the entire bottom perimeter of the spoiler. Attach in a way that the strips basically create a single uninterrupted edge. This will prevent the intrusion of water below the spoiler which over time will result in deteriorating the adhesive, dirt/moisture buildup and detachment. 5. Once adhesive tape is fully applied around the bottom perimeter of the spoiler, mark off the vehicle area where it will be applied. Tape is very sticky and its best to place it correctly the first time around. I had to try twice and remove/reapply tape in a corner and I am pretty good at this sort of stuff. Again PATIENCE required. 6. Remove red side of ALL double-sided adhesive tape. 7. Attach spoiler lightly and try to get it in desired placement in the first try. Once correctly placed, press down firmly and you are all set. 8. Wax spoiler and surrounding trunk area where alcohol was applied. Rewax again a few days later. This will seal/protect the spoiler paint. Several reviews point out peeling spoiler paint which may be attributed to leaving it naked. Waxing will protect from UV, heat and contamination exposure and prolong life. If you find above to be a challenge, seek installation with a window film, detailer, delete black-out technician. These guys are very well practiced for these types of jobs and have incredible talent and patience. And the service is not expensive.
Review: Perfect fit and finish. - Install was easy. It does include 3M tape. No instruction but if you have made it this far you probably have access to YouTube. The color is good, size and fit is perfect. Can’t really speak on the durability of the paint yet. However I ceramic coated it for added protection. Overall I’m very happy with the spoiler. This installed my my G22 coupe.

### ⭐⭐⭐⭐⭐ Superb product, adhesive tape strips take attention to install properly, but looks great.
*by A***R on July 11, 2023*

Made a huge and noticeable difference in the look of the back side of my white 2020 BMW 430i. It finishes the visual line of the car off from a very nice front to a relatively uninspired back, and when installed it just makes the car look great all the way through, for very little money, I am very happy with the product and how it really noticeably and positively finished off the look of my car perfectly.
