What is the function of a car front lip?

Most vehicle front lips serve only a decorative purpose. Installing a front lip can make the car look more aesthetically pleasing, but its practical effect is actually minimal—it merely adds a bit of personality to the vehicle's appearance. To avoid being stopped by traffic police, it's best not to modify it. Below is an introduction to the materials used for car front lip kits: 1. Introduction one: The cheapest option is resin fiber, also known as fiberglass. It is relatively brittle and has decent formability, but it is not suitable for automotive exterior kits. These items are very low-cost, so the surface finish is also poor. After purchase, you must apply putty and paint to cover imperfections. 2. Introduction two: A better option is commonly seen one-time molded PP material, which is ABS engineering plastic. This material has slight flexibility, but its elasticity is limited. It is heat-resistant and not prone to deformation, but it is relatively hard. The craftsmanship is better, giving it a high-end appearance, and it is generally used for small car kits or parts close to the ground. 3. Introduction three: Another commonly used material is PU, or soft rubber, which is highly flexible and resistant to scratches and damage. However, it cannot withstand high-temperature paint baking and is prone to deformation. It is also relatively thick and heavy.

I've been into car modifications for about seven or eight years, and the front lip is a popular part among many car enthusiasts. It's installed at the very bottom of the front end, resembling a shovel, and its functionality goes beyond what one might expect. For instance, after installing a carbon fiber front lip on my car, the front end became noticeably more stable at high speeds because the airflow was directed to both sides under the car. But the most practical benefit is its protective function—once, when I scraped against a curb in a parking lot, the front lip took the hit first, leaving the bumper's paint unscathed. However, with the reduced ground clearance, you have to be extra careful when going over speed bumps. I once drove too fast and ended up scraping and cracking an aftermarket part, which was heartbreaking. Now, I advise newcomers to measure the clearance for their daily driving conditions before making any modifications.

Last time when I helped my uncle fix his car, I noticed a new scratch under the front bumper. He said it was from driving on rough country roads. I directly installed an ABS plastic front lip for him, mainly as a protective panel. These hard plastic parts costing just a few dozen bucks are particularly scratch-resistant, and even gravel impacts won't leave marks. After installation, the front end looks a bit lower, and my uncle even said it feels more stylish. However, it's worth noting that if the original mounting points aren't secure enough, the lip can easily be washed off when driving through waterlogged sections. It's best to reinforce it with self-tapping screws inside the wheel arches.

The front splitter actually helps with handling. This year while driving on mountain roads, I noticed that cars with front splitters have better front axle grip, especially when navigating hairpin turns where understeer is less likely. The principle is simple: high-speed airflow passing over the top edge of the splitter creates a low-pressure zone, pulling the front of the car downward. However, the effect is limited in daily street driving; it's barely noticeable below 80 km/h. To truly utilize its function, it needs to be paired with side skirts and a rear diffuser. Installing it alone is mostly for visual appeal. Nowadays, even some new energy vehicles feature hidden front splitters, concealed below the air intake.
