I can't even think what will happen with pedestrian legs if you hit him with this. I have to admit. They look nice, but nothing more than that.
An air dam a. It is sometimes called a "front lip" or "lip spoiler. Unlike the splitter, the lip is not a flat "sheet" of material. Function of both are the same, to create lover and higher pressure areas, but in case of air dam, in less extreme way. Formula 1 splitter is known by many names, such as the shadow or legality plate, T-tray or bib. In the late eighties when designers were slimming and raising the nose of the cars , there was a need to create a floor section under the front of the monocoque to meet the flat bottom rules.
The first splitter used in Formula 1 was with the Tyrrell with its fully raised nose. Since then the spli tter has been more and more exposed as teams seek to raise and narrow the chassis cross section for aerodynamic benefit.
Formula 1 splitters regulatory role has been intended to form the flat bottom of the car and form an attachment for the plank running along the length of the flat floor. Splitter must form the flat floor at reference plane level. The splitter must also shadow the plan profile of the monocoque, such that the monocoque can not be viewed from beneath the splitter.
Original intention of FIA was only that. However, as everything in Formula 1, this bodywork forming the floor has been exploited and the splitter now forms aerodynamic and chassis functions of its own.
As the term suggests the splitter separates split the airflow passing under the raised nose to two separate airflows. One pasing above and one pasing below the floor. On the upper part of the splitter, on the point where splitter meets monocoque, there is bow shape. Air spills under and over the spliter. Teams make use of this powerful flow to alter the air pressure distribution across and over the underfloor to further improve airflow through the diffuser.
Together with fences, vortex generators and previously bargeboards , the splitter forms a critical role in the onset flow for the diffuser. Being mounted low and far forward, the splitter also forms good location for ballast. With a rear engine car, the only way to do this is to ballast the front of the car and the splitter has been known to be made entirely from metal in order to maximise front end weight bias. Since the season-opener in Australia, there has been much talk of 'movable' floors on Formula One cars.
Teams are developing a way to mount the splitter in such a way that it will pass the standard deflection test during the scrutineering , but then lift under greater aerodynamic loads at speed on the circuit, providing significant aerodynamic gains.
All teams were working on that, but only Ferarri and BMW have a guts to actually run it. If you introduce a way to allow the car's bib to lift at high speed, it will lead to stall of underbody aerodynamics.
That means that the airflow passing through the diffuser no longer closely follows the diffuser's profile. Instead, at a certain point - determined by air pressure levels close to the diffuser wall - the airflow detaches and proceeds on its own horizontal trajectory.
And that lead to less drag with less downforce. Read more about movable floor in my article here. F1 rules deem that the front area of this splitter T-tray, bib needs to be shaped in a certain way.
Article For most of the s, there seems to have been two fundamental way ot thinking about front-end aerodynamic concept of Formula 1 cars. This latter group included teams such as March, Brabham and Tyrrell, with Jackie Stewart winning the and World Championships in Tyrrell designs with just such a front-end designe. So what was the idea?
Well, part of the motivation was presumably to reduce the lift, drag and turbulence created by the front wheels. The front spoilers were much wider than front wings, and partially shrouded the front wheels, diverting airflow over and around the wheels. So that was part of the idea. The other possible motive is perhaps more interesting, because it involves ground-effect. The photo here shows a Tyrrell 6 wheeler running quite a degree of rake , which would serve to accentuate the ground-effect of the front spoiler.
And in fact, Gordon Murray began experimenting with ground-effect on the Brabham BT44 back in , arriving at "an inch-deep underbody vee, something like a front airdam, but halfway down the car. The introduction of underbody venturi and skirts presumably spelt the death sentence for front spoilers, as the emphasis then shifted to feeding the underbody with as much airflow as possible.

It is very unlikely that a splitter or diffuser will have any measurable benefit unless you are driving a car that is: Very low to the ground over a Very smooth surface at a Very high speed.

Ideally, you want a height-adjustable coilover suspension or an air suspension.
Now that you know how a car splitter works, consider if one would be a good mod for your car. June 12, What Is a Car Splitter? Carbon fiber splitters are the strongest, but they are also the most expensive. Air Resistance When a car is in motion, it has to push through air resistance. Overflow and Underflow Balance The incoming air that hits the front of a car when it is accelerating has its own velocity and pressure.
