I would absolutely LOVE to be able to have access to a full scale wind tunnel for testing. But on avg you spend a few thousand dollars an hour on a wind tunnel to rent, and that is just not feasible to be honest.
This image I found on line should give you a better visualization of what happens. And on a automotive application...yes I know its a EVO, but this is a very good visualization of what is going on. And the fact that air foils work based on air flow differences, the more flow you pass under the lower surface of a wing vs the upper surface on a car the more downforce it generates. Would love to go into more detail about air foils, fluid dymanics, aerodynamics and so forth. It would get quite nerdy quickly and actually stray away from automotive application and require mathematics and physics background. Kirill RallySportDirect.com

Just noticed, when it is installed is there a gap between it and the roof rails? Will you still be able to see the color of the car in that space?

They do not sit 100% even with the back, so there is a space to move it a little more left or right along with forward and back.

i flipped through this, and didnt see a mention of this. but what is with the rear training arms from cusco? why do the parts from the stock photo look so beefy and the parts on the car look so dinky?

The first image that you posted is for the GD unit, and that is the 2002-2007 WRX/STi trailing arm.
http://www.rallysportdirect.com/Cusc...7&src=vr7oueah The 2008-2013 STi trailing arms are different. http://www.rallysportdirect.com/Cusc...m&src=vr7oueah Unless you are asking about the lateral links, in that case they are also different between the GD and GR chassis http://www.rallysportdirect.com/Cusc...k&src=vr7oueah Vs (GD WRX and STi Lateral Links are different, and you buy the front and rear trailing arms separate for the rear suspension) http://www.rallysportdirect.com/Cusc...7&src=vr7oueah http://www.rallysportdirect.com/Cusc...7&src=vr7oueah Hope this helps Kirill RallySportDirect.com |

The first image I posted was taken from earlier in this thread. You posted it.
Still, the new arms look rather weak IMO. Also the GR does not have lateral links. They are lower control arms |

"looks" can be deceiving. There are plenty stout for the job that they are designed to do. We have never seen or heard of a single failure of this component in all the years that it has been available Quote:

i guess i dont really understand the design. adjustability is fine, but this arm looks a good bit shorter than stock. id be worried about running out of threads on a lifted setup.
also the stock arm is clearly bent for clearance around the toe arm, with the cusco straight. just disappointed with the design i guess :/. i do like the rear LCAs though. ive been keeping my eye out for a reasonably priced set. |

Yes the stock arm is bent, but as you can see in the above image its also a stamped steel piece that gets its rigidity by being a box construction. This method of manufacturing cuts costs and increases production rate at the factory, however as you can tell also has a larger overall size as a result. The Cusco unit is able to get away with being straight due to its compact design which gains its strength from the wall thickness of the bar. Its been years from when I installed them on the shop STI, but I do recall that these Cusco units were heavier and "beefier" construction. As you can see in the below image, there is plenty of clearance to the toe arm with the Cusco unit. We have ran the STi at a drop height of -2.5" lower then stock with no issues, and currently have the Whiteline toe adjustable arms that are larger then the stock toe arms. With about 1" of clearance between the toe arm and the Cusco arm. And that clearance between the 2 arms will not change at ride height changes any significant amount. Kirill RallySportDirect.com |

Another pic of it staying nice and warm in our showroom. Only a few more weeks left until we bring it out. Stupid winter and salt

We took the STi and the Rhino out for some laps around Miller Motorsports Park yesturday evening .
Good times! Both cars need set up, but gave us a chance to get a good idea where to start (we will have some non cell phone pics up shortly) Kirill RallySportDirect.com |

We have also been busy with some other cars as well
Here is the lineup of our Current shop cars. We dont hate here, and appreciate! All of these cars are a blast, and have their own unique personality and advantages |

We did not not do any timing, and didnt go all out with the cars around the track. Its quite apparent work is needed to set them up to improve handling so there is no point in pushing it when you know the set up is not optimal.

What's with picking up 3 new shop cars in the last what month though? Isn't that going to take time away from dialing each in?

I love seeing that some research has actually been done here to substantiate the theory of VGs. I'm scratching my head a bit though (and this is just curiosity, not criticism), because in order for vortex generators to do what they're supposed to, shouldn't they be oriented at an angle to the relative airflow, as they are on airplane wings? If the vanes are mostly aligned with the airflow, where does the vortex come from? I would really like to see a car driven with a fully tufted rear windshield to see the airflow with and without VGs attached. The theory is sound, but I don't know if it's being applied correctly in most of these aftermarket parts.

As for testing, you and me both! Problem is that to have a wind tunnel large enough to test something like accurately would cost more then the manufacture could ever re-couple from selling the product. So most of this testing is done in CFD due to cost. With that being said, I know that Mitsubishi did a large amount of testing with this(EVO images were actually from MHI) to make improvements to the EVO IX over the EVO VIII in terms of aerodynamics and was implemented in the MR models as well. Hope this helps a bit. Kirill RallySportDirect.com |
