BODYKITS

Bodykits/ Aerokits have been popular for many years. The two main objectives of a bodykit are to enhance aerodynamics and to enhance/modify the appearance of your vehicle. AEROKIT have various manufacturing techniques for the different types of Bodykit use, for example our SPEC D series are reinforced in areas which are prone to impact, our SPEC R series bodykits are made with a lighter resin to achieve a lighter product. So how does a bodykit enhance the aerodynamics of a car then?.... Downforce.....read on....

ITS ALL ABOUT DOWNFORCE!

So what is downforce? why do i need it and how do i achieve it?............

See wikipedia for the full article:

The same principle that allows an airplane to rise off the ground by creating lift from its wings is used in reverse to apply force that presses the race car against the surface of the track. This effect is referred to as "aerodynamic grip" and is distinguished from "mechanical grip," which is a function of the car mass repartition, tires and suspension. The creation of downforce by passive devices almost always can only be achieved at the cost of increased aerodynamic drag (or friction), and the optimum setup is almost always a compromise between the two. The aerodynamic setup for a car can vary considerably between race tracks, depending on the length of the straights and the types of corners; some drivers also make different choices on setup. Because it is a function of the flow of air over and under the car, and because aerodynamic forces increase with the square of velocity, downforce increases with the square of the car's speed and requires a certain minimum speed in order to produce a significant effect. But some cars have had rather unstable aerodynamics, such that a minor change in angle of attack or height of the vehicle and this can cause large changes in the downforce. In the very worse cases the can cause the car to experience lift, not downforce, for example, caused by a bump on the track or slipstreaming over a crest, and sometimes can have disastrous consequences. A notorious example of this was Peter Dumbreck's Mercedes-Benz CLR in the 1999 Le Mans 24 hours, which flipped spectacularly after closely following a competitor car over a hump.

DIFFUSERS

So what are diffusers and what do they do? Brought into the spotlight in 2009 during the F-1 season diffusers can undoubtedly increase downforce on track, how?......As a vehicle moves forwards it cuts into the air displacing the air molecules. With this movement the air molecules nearer the rear of the vehicle are disrupted more vigorously. This produces a higher rate of disrupted air molecules which results in vehicle ‘lift’ which is something you do not want when driving at high speeds. What you are trying to achieve with aero parts is ‘downforce’. With a diffuser in place the disrupted air molecules which are moving towards the rear of the car are channeled through the diffuser which lessens the rate of disrupted air molecules generating cleaner air thus providing more ‘downforce’. As a result acceleration and control is increased significantly. 

To put it simple, diffusers clean up the disrupted air at the rear which achieves higher acceleration, control and stability.......and of course they look damn good!
