whats the function of the splitter? sorry dumb question is it so your front bumper wont scracth on the ground or does it have something to do with air
A front splitter serves many purposes. As I plan on doing a how-to on my car in the future, this seemed like a great opportunity to list some of the performance benifits of adding one of these beauties...
first off, there is the issue of aerodynamics. A splitter is far more than just a wing. to explain, we look at another high-speed vehicle, the fighter jet.
In the early days of aeronautics, fighter jets had simple nose cones much like this:
pilots noticed that, at high speeds, the jets of the day would shake violently, this was due to an aerodynamic principle called "suface drag". apparently, air flowing along the skin of the aircraft was so turbulent, and put so much resistance on the skin of the airplane, vortices and ripples caused by an irregular flow of air when the nose of the plane would break through the atmosphere. the fix was a simple one, they added a long antenna-like probe to the nosecone like this:
The Splitter was born.
Splitters on a car do the same thing, they help to initially penetrate the air, allowing it to flow around the front-end of your airdam, and your car, with less surface drag. this allows for better handling at speed. A good comparison for a splitter vs. no splitter is the difference between a small-gauge syringe when getting a booster shot, and using a large knitting needle to give an injection. Am I making sense so far?
Seccond advantage, it helps protect the front bumper from scrapes and such. it's cheaper to replace the splitter than it is to respray the front bumper.
Another benifit is the ability to tune aerodynamic performance by adjusting the splitter to produce more or less drag, as well as fine-tuning downforce.
A splitter also helps re-direct air under the engine bay, helping to keep things cooler (like a hoodscoop under the car...)
all that holds true, plus it looks cool.
Just be sure to make rear aerodynamic adjustments to accompany your new splitter. For example, I will be adjusting my TRD
spoiler to give more downforce in the rear once I add the splitter. having your nose grip hard at speed with a loose back end can be bad.
