What is a front lip and why would you want one?
What is the reason for all the interest in this part of an automobile?There are two main reasons. One practice is and the other is cosmetic.From a practical point of view of a vehicle moving through the air sometimes acts like an airplane. In other words, the air flow in a car or truck moves from a slightly shorter distance than the air flow on the top of the vehicle. This difference causes a pressure differential, with the low pressure at the top of the vehicle.This means that there is more pressure trying to lift the car, keep the car on the road. The weight of the car is sufficient in most circumstances to overcome this tendency to raise. However, moving the car fairly quickly and thus increase the airflow and interesting things can happen. Just like a plane taking off, enough speed is enough lift and you are in charge of the air.This is good for an aircraft is a disaster for a car. If you ever look at photos of car races, you might see a picture of a fast moving race car suddenly raise in its front end and sometimes completely turn upside down.The front spoiler or lip or air dam is designed to stop this dangerous air flow on a racing car or an exotic car that is capable of very high speeds.The second reason these devices are added to the car's style. People like to feel they are driving a fast car. They want the appearance even if they will never push the car at speeds that require an aerodynamic device like this. If you look at most of the new cars you will see some type of extension below the front bumper. It is for the design and not to hold the front end of the car down.Given that all cars come with this look, now is a large secondary market which designs and builds lips, spoilers and air dams for people who want to dress their pride and joy.Is it all positive? No, there are a couple of things to keep in mind. First, this additional weight is at the front end of the car. It should not make a difference, but if you add a heavy weight at the front end, you can change the handling characteristics of a car. Second, you now reduces the distance of the front end on the sidewalk. On a level road, there should be no problem. However, hit a dip, or a large parking block, or even a steep driveway and you can find your front end is dragging on the ground.The last caveat is installation. Most alternative products like this require a certain amount of expertise to fit correctly. If you do not have this experience, find a professional for installation.
