Improving your vehicles downforce

3 August 2011 10 Comments

Being a bit of the track day enthusiast I am always looking for new ways to improve on my cars handling and performance. I’ve been doing quite a bit of research on down force and aerodynamics.

Wings, Splitters and Diffusers all play an important role when it comes to helping with down force and improving your cars aerodynamics. At the end of the day this all benefits your vehicles handling.

In this blog we will hopefully convince you to improve your aerodynamics on your vehicle and add a bit of flare to your car. All though these parts mentioned bellow are used to improve your aerodynamics they can also be used to improve your cars appearance and styling.

I’m not sure if you guys have noticed, but more and more high performance cars are using Canards, these are little winds that have been developed to fit onto your cars front bumper to help improve the down force at the front of your vehicle. Another popular form of generating down force is to use front splitters, the splitters get mount to the underneath of you front bumper and help channel the vehicles turbulence. Improving the downforce in the front of your car can also improve your vehicles performance.
If you think about it, the more downforce you have at the front of your car the less chance of your car loosing traction under acceleration, however this only applies to Front Wheel Drive cars. Rear Wheel Drive cars need to fit either a Diffusers, rear wings, vortex generator or sand bags( I’m only joking about the sand bags). For those that don’t know, a Diffuser is a piece of sheet metal that has been developed in such a way that it directs the turbulence generated by your vehicle in positive way. Diffusers can also be found come on a lot of High performance cars these days but are molded into the rear bumper from the factory. A Vortex Generator is found a lot these days on Subaru’s and Mitsubishi Evo’s and is placed on the top rear of your roof, in a nut shell it does the same as the diffuser except its located on the top of your car.

Having these different Aerodynamic enhancers on your vehicle will create more downforce and improve your vehicles handling. However there is a but! Is your car fast enough to actually notice that extra down force.

    What shape is your Honda Tashriq and what kind of power is your car producing? The wing should stabilise the car a lot more
